Dockerfile to build a Redmine container image.

Current Version: 3.0.1

P.S.: If your installation depends on various third party plugins, please stick with 2.6.xx series to avoid breakage.

If you find this image useful here's how you can help:

• Send a Pull Request with your awesome new features and bug fixes
• Help new users with Issues they may encounter
• Send me a tip via Bitcoin or using Gratipay

Docker is a relatively new project and is active being developed and tested by a thriving community of developers and testers and every release of docker features many enhancements and bugfixes.

Given the nature of the development and release cycle it is very important that you have the latest version of docker installed because any issue that you encounter might have already been fixed with a newer docker release.

For ubuntu users I suggest installing docker using docker's own package repository since the version of docker packaged in the ubuntu repositories are a little dated.

Here is the shortform of the installation of an updated version of docker on ubuntu.

sudo apt-get purge docker.io
curl -s https://get.docker.io/ubuntu/ | sudo sh
sudo apt-get update
sudo apt-get install lxc-docker

Fedora and RHEL/CentOS users should try disabling selinux with setenforce 0 and check if resolves the issue. If it does than there is not much that I can help you with. You can either stick with selinux disabled (not recommended by redhat) or switch to using ubuntu.

If using the latest docker version and/or disabling selinux does not fix the issue then please file a issue request on the issues page.

In your issue report please make sure you provide the following information:

• The host distribution and release version.
• Output of the docker version command.
• Output of the docker info command.
• The docker run command you used to run the image (mask out the sensitive bits).

Pull the image from the docker index. This is the recommended method of installation as it is easier to update image in the future. These builds are performed by the Trusted Build service.

docker pull sameersbn/redmine:latest

Since version 2.4.2, the image builds are being tagged. You can now pull a particular version of redmine by specifying the version number. For example,

docker pull sameersbn/redmine:3.0.1

Alternately you can build the image yourself.

git clone https://github.com/sameersbn/docker-redmine.git
cd docker-redmine
docker build --tag="$USER/redmine" .

You can launch the image using the docker command line,

docker run --name=redmine -it --rm -p 10080:80 \
-v /var/run/docker.sock:/run/docker.sock \
-v $(which docker):/bin/docker \
sameersbn/redmine:3.0.1

Or you can use fig. Assuming you have fig installed,

wget https://raw.githubusercontent.com/sameersbn/docker-redmine/master/fig.yml
fig up

The rest of the document will use the docker command line. You can quite simply adapt your configuration into a fig.yml file if you wish to do so.

NOTE: Please allow a minute or two for the Redmine application to start.

Point your browser to http://localhost:10080 and login using the default username and password:

• username: admin
• password: admin

You should now have the Redmine application up and ready for testing. If you want to use this image in production the please read on.

For the file storage we need to mount a volume at the following location.

• /home/redmine/data

NOTE

Existing users need to move the existing files directory inside /opt/redmine/data/.

mkdir -p /opt/redmine/data
mv /opt/redmine/files /opt/redmine/data

SELinux users are also required to change the security context of the mount point so that it plays nicely with selinux.

mkdir -p /opt/redmine/data
sudo chcon -Rt svirt_sandbox_file_t /opt/redmine/data

Volumes can be mounted in docker by specifying the '-v' option in the docker run command.

docker run --name=redmine -it --rm \
  -v /opt/redmine/data:/home/redmine/data sameersbn/redmine:3.0.1

Redmine uses a database backend to store its data.

The internal mysql server has been removed from the image. Please use a linked mysql or postgresql container instead or connect with an external mysql or postgresql server.

If you have been using the internal mysql server follow these instructions to migrate to a linked mysql container:

Assuming that your mysql data is available at /opt/redmine/mysql

docker run --name=mysql -d \
  -v /opt/redmine/mysql:/var/lib/mysql \
  sameersbn/mysql:latest

This will start a mysql container with your existing mysql data. Now login to the mysql container and create a user for the existing redmine_production database.

All you need to do now is link this mysql container to the redmine container using the --link mysql:mysql option and provide the DB_NAME, DB_USER and DB_PASS parameters.

Refer to Linking to MySQL Container for more information.

The image can be configured to use an external MySQL database instead of starting a MySQL server internally. The database configuration should be specified using environment variables while starting the Redmine image.

Before you start the Redmine image create user and database for redmine.

mysql -uroot -p
CREATE USER 'redmine'@'%.%.%.%' IDENTIFIED BY 'password';
CREATE DATABASE IF NOT EXISTS `redmine_production` DEFAULT CHARACTER SET `utf8` COLLATE `utf8_unicode_ci`;
GRANT SELECT, LOCK TABLES, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER ON `redmine_production`.* TO 'redmine'@'%.%.%.%';

We are now ready to start the redmine application.

docker run --name=redmine -it --rm \
  -e "DB_HOST=192.168.1.100" -e "DB_NAME=redmine_production" \
  -e "DB_USER=redmine" -e "DB_PASS=password" \
  -v /opt/redmine/data:/home/redmine/data sameersbn/redmine:3.0.1

This will initialize the redmine database and after a couple of minutes your redmine instance should be ready to use.

You can link this image with a mysql container for the database requirements. The alias of the mysql server container should be set to mysql while linking with the redmine image.

If a mysql container is linked, only the DB_TYPE, DB_HOST and DB_PORT settings are automatically retrieved using the linkage. You may still need to set other database connection parameters such as the DB_NAME, DB_USER, DB_PASS and so on.

To illustrate linking with a mysql container, we will use the sameersbn/mysql image. When using docker-mysql in production you should mount a volume for the mysql data store. Please refer the README of docker-mysql for details.

First, lets pull the mysql image from the docker index.

docker pull sameersbn/mysql:latest

For data persistence lets create a store for the mysql and start the container.

SELinux users are also required to change the security context of the mount point so that it plays nicely with selinux.

mkdir -p /opt/mysql/data
sudo chcon -Rt svirt_sandbox_file_t /opt/mysql/data

The run command looks like this.

docker run --name=mysql -d \
  -e 'DB_NAME=redmine_production' -e 'DB_USER=redmine' -e 'DB_PASS=password' \
  -v /opt/mysql/data:/var/lib/mysql \
  sameersbn/mysql:latest

The above command will create a database named redmine_production and also create a user named redmine with the password password with full/remote access to the redmine_production database.

We are now ready to start the redmine application.

docker run --name=redmine -it --rm --link mysql:mysql \
  -v /opt/redmine/data:/home/redmine/data \
  sameersbn/redmine:3.0.1

Here the image will also automatically fetch the DB_NAME, DB_USER and DB_PASS variables from the mysql container as they are specified in the docker run command for the mysql container. This is made possible using the magic of docker links and works with the following images:

• sameersbn/mysql
• centurylink/mysql
• orchardup/mysql

The image also supports using an external PostgreSQL Server. This is also controlled via environment variables.

CREATE ROLE redmine with LOGIN CREATEDB PASSWORD 'password';
CREATE DATABASE redmine_production;
GRANT ALL PRIVILEGES ON DATABASE redmine_production to redmine;

We are now ready to start the redmine application.

docker run --name=redmine -it --rm \
  -e "DB_TYPE=postgres" -e "DB_HOST=192.168.1.100" \
  -e "DB_NAME=redmine_production" -e "DB_USER=redmine" -e "DB_PASS=password" \
  -v /opt/redmine/data:/home/redmine/data \
  sameersbn/redmine:3.0.1

This will initialize the redmine database and after a couple of minutes your redmine instance should be ready to use.

You can link this image with a postgresql container for the database requirements. The alias of the postgresql server container should be set to postgresql while linking with the redmine image.

If a postgresql container is linked, only the DB_TYPE, DB_HOST and DB_PORT settings are automatically retrieved using the linkage. You may still need to set other database connection parameters such as the DB_NAME, DB_USER, DB_PASS and so on.

To illustrate linking with a postgresql container, we will use the sameersbn/postgresql image. When using postgresql image in production you should mount a volume for the postgresql data store. Please refer the README of docker-postgresql for details.

First, lets pull the postgresql image from the docker index.

docker pull sameersbn/postgresql:latest

For data persistence lets create a store for the postgresql and start the container.

SELinux users are also required to change the security context of the mount point so that it plays nicely with selinux.

mkdir -p /opt/postgresql/data
sudo chcon -Rt svirt_sandbox_file_t /opt/postgresql/data

The run command looks like this.

docker run --name=postgresql -d \
  -e 'DB_NAME=redmine_production' -e 'DB_USER=redmine' -e 'DB_PASS=password' \
  -v /opt/postgresql/data:/var/lib/postgresql \
  sameersbn/postgresql:latest

The above command will create a database named redmine_production and also create a user named redmine with the password password with access to the redmine_production database.

We are now ready to start the redmine application.

docker run --name=redmine -it --rm --link postgresql:postgresql \
  -v /opt/redmine/data:/home/redmine/data \
  sameersbn/redmine:3.0.1

Here the image will also automatically fetch the DB_NAME, DB_USER and DB_PASS variables from the postgresql container as they are specified in the docker run command for the postgresql container. This is made possible using the magic of docker links and works with the following images:

• postgres
• sameersbn/postgresql
• orchardup/postgresql
• paintedfox/postgresql

This image can (optionally) be configured to use a memcached server to speed up Redmine. This is particularly useful when you have a large number users.

The image can be configured to use an external memcached server. The memcached server host and port configuration should be specified using environment variables MEMCACHE_HOST and MEMCACHE_PORT like so:

Assuming that the memcached server host is 192.168.1.100

docker run --name=redmine -it --rm \
  -e 'MEMCACHE_HOST=192.168.1.100' -e 'MEMCACHE_PORT=11211' \
  sameersbn/redmine:3.0.1

Alternately you can link this image with a memcached container. The alias of the memcached server container should be set to memcached while linking with the redmine image.

To illustrate linking with a memcached container, we will use the sameersbn/memcached image. Please refer the README of docker-memcached for details.

First, lets pull and launch the memcached image from the docker index.

docker run --name=memcached -d sameersbn/memcached:latest

Now you can link memcached to the redmine image:

docker run --name=redmine -it --rm --link memcached:memcached \
  sameersbn/redmine:3.0.1

The mail configuration should be specified using environment variables while starting the redmine image. The configuration defaults to using gmail to send emails and requires the specification of a valid username and password to login to the gmail servers.

Please refer the Available Configuration Parameters section for the list of SMTP parameters that can be specified.

docker run --name=redmine -it --rm \
  -e "[email protected]" -e "SMTP_PASS=PASSWORD" \
  -v /opt/redmine/data:/home/redmine/data sameersbn/redmine:3.0.1

If you are not using google mail, then please configure the SMTP host and port using the SMTP_HOST and SMTP_PORT configuration parameters.

NOTE:

I have only tested standard gmail and google apps login. I expect that the currently provided configuration parameters should be sufficient for most users. If this is not the case, then please let me know.

Access to the redmine application can be secured using SSL so as to prevent unauthorized access. While a CA certified SSL certificate allows for verification of trust via the CA, a self signed certificates can also provide an equal level of trust verification as long as each client takes some additional steps to verify the identity of your website. I will provide instructions on achieving this towards the end of this section.

To secure your application via SSL you basically need two things:

• Private key (.key)
• SSL certificate (.crt)

When using CA certified certificates, these files are provided to you by the CA. When using self-signed certificates you need to generate these files yourself. Skip the following section if you are armed with CA certified SSL certificates.

Jump to the Using HTTPS with a load balancer section if you are using a load balancer such as hipache, haproxy or nginx.

Generation of self-signed SSL certificates involves a simple 3 step procedure.

STEP 1: Create the server private key

openssl genrsa -out redmine.key 2048

STEP 2: Create the certificate signing request (CSR)

openssl req -new -key redmine.key -out redmine.csr

STEP 3: Sign the certificate using the private key and CSR

openssl x509 -req -days 365 -in redmine.csr -signkey redmine.key -out redmine.crt

Congratulations! you have now generated an SSL certificate thats valid for 365 days.

This section provides you with instructions to strengthen your server security. To achieve this we need to generate stronger DHE parameters.

openssl dhparam -out dhparam.pem 2048

Out of the four files generated above, we need to install the redmine.key, redmine.crt and dhparam.pem files at the redmine server. The CSR file is not needed, but do make sure you safely backup the file (in case you ever need it again).

The default path that the redmine application is configured to look for the SSL certificates is at /home/redmine/data/certs, this can however be changed using the SSL_KEY_PATH, SSL_CERTIFICATE_PATH and SSL_DHPARAM_PATH configuration options.

If you remember from above, the /home/redmine/data path is the path of the data store, which means that we have to create a folder named certs inside /opt/redmine/data/ and copy the files into it and as a measure of security we will update the permission on the redmine.key file to only be readable by the owner.

mkdir -p /opt/redmine/data/certs
cp redmine.key /opt/redmine/data/certs/
cp redmine.crt /opt/redmine/data/certs/
cp dhparam.pem /opt/redmine/data/certs/
chmod 400 /opt/redmine/data/certs/redmine.key

Great! we are now just one step away from having our application secured.

HTTPS support can be enabled by setting the REDMINE_HTTPS option to true.

docker run --name=redmine -d \
  -e 'REDMINE_HTTPS=true' \
  -v /opt/redmine/data:/home/redmine/data \
  sameersbn/redmine:3.0.1

In this configuration, any requests made over the plain http protocol will automatically be redirected to use the https protocol. However, this is not optimal when using a load balancer.

HSTS if supported by the browsers makes sure that your users will only reach your sever via HTTPS. When the user comes for the first time it sees a header from the server which states for how long from now this site should only be reachable via HTTPS - that's the HSTS max-age value.

With REDMINE_HTTPS_HSTS_MAXAGE you can configure that value. The default value is 31536000 seconds. If you want to disable a already sent HSTS MAXAGE value, set it to 0.

docker run --name=redmine -d \
  -e 'REDMINE_HTTPS=true' \
  -e 'REDMINE_HTTPS_HSTS_MAXAGE=2592000'
  -v /opt/redmine/data:/home/redmine/data \
  sameersbn/redmine:3.0.1

If you want to completely disable HSTS set REDMINE_HTTPS_HSTS_ENABLED to false.

Load balancers like nginx/haproxy/hipache talk to backend applications over plain http and as such the installation of ssl keys and certificates are not required and should NOT be installed in the container. The SSL configuration has to instead be done at the load balancer. Hoewever, when using a load balancer you MUST set REDMINE_HTTPS to true.

With this in place, you should configure the load balancer to support handling of https requests. But that is out of the scope of this document. Please refer to Using SSL/HTTPS with HAProxy for information on the subject.

When using a load balancer, you probably want to make sure the load balancer performs the automatic http to https redirection. Information on this can also be found in the link above.

In summation, when using a load balancer, the docker command would look for the most part something like this:

docker run --name=redmine -d -p 10080:80 \
  -e 'REDMINE_HTTPS=true' \
  -v /opt/redmine/data:/home/redmine/data \
  sameersbn/redmine:3.0.1

By default redmine expects that your application is running at the root (eg. /). This section explains how to run your application inside a directory.

Let's assume we want to deploy our application to '/redmine'. Redmine needs to know this directory to generate the appropriate routes. This can be specified using the REDMINE_RELATIVE_URL_ROOT configuration option like so:

docker run --name=redmine -d -p 10080:80 \
  -e 'REDMINE_RELATIVE_URL_ROOT=/redmine' \
  -v /opt/redmine/data:/home/redmine/data \
  sameersbn/redmine:3.0.1

Redmine will now be accessible at the /redmine path, e.g. http://www.example.com/redmine.

Note: The REDMINE_RELATIVE_URL_ROOT parameter should always begin with a slash and SHOULD NOT have any trailing slashes.

docker run --name=redmine -d -h redmine.local.host \
  -v /opt/redmine/data:/home/redmine/data \
  -v /opt/redmine/mysql:/var/lib/mysql \
  -e "[email protected]" -e "SMTP_PASS=PASSWORD" \
  sameersbn/redmine:3.0.1

If you are using an external mysql database

docker run --name=redmine -d -h redmine.local.host \
  -v /opt/redmine/data:/home/redmine/data \
  -e "DB_HOST=192.168.1.100" -e "DB_NAME=redmine_production" -e "DB_USER=redmine" -e "DB_PASS=password" \
  -e "[email protected]" -e "SMTP_PASS=PASSWORD" \
  sameersbn/redmine:3.0.1

Please refer the docker run command options for the --env-file flag where you can specify all required environment variables in a single file. This will save you from writing a potentially long docker run command.

The functionality of redmine can be extended using plugins developed by the community. You can find a list of available plugins in the Redmine Plugins Directory. You can also search for plugins on github.

Please check the plugin compatibility with the redmine version before installing a plugin.

Plugins should be installed in the plugins directory at the data store. If you are following the readme verbatim, on the host this location would be /opt/redmine/data/plugins.

mkdir -p /opt/redmine/data/plugins

To install a plugin, simply copy the plugin assets to the plugins directory. For example, to install the recurring tasks plugin:

cd /opt/redmine/data/plugins
git clone https://github.com/nutso/redmine-plugin-recurring-tasks.git

For most plugins this is all you need to do. With the plugin installed you can start the docker image normally. The image will detect that a plugin has been added (or removed) and automatically install the required gems and perform the plugin migrations and will be ready for use.

If the gem installation fails after adding a new plugin, please retry after removing the /opt/redmine/data/tmp directory

Some plugins however, require you to perform additional configurations to function correctly. You can add these steps in a init script at the /opt/redmine/data/plugins directory that will executed everytime the image is started.

For example, the recurring tasks plugin requires that you create a cron job to periodically execute a rake task. To achieve this, create the /opt/redmine/data/plugins/init file with the following content:

## Recurring Tasks Configuration

# get the list existing cron jobs for the redmine user
crontab -u redmine -l 2>/dev/null >/tmp/cron.redmine

# add new job for recurring tasks if it does not exist
if ! grep -q redmine:recur_tasks /tmp/cron.redmine; then
  echo '@hourly cd /home/redmine/redmine && bundle exec rake redmine:recur_tasks RAILS_ENV=production >> log/cron_rake.log 2>&1' >>/tmp/cron.redmine
  crontab -u redmine /tmp/cron.redmine 2>/dev/null
fi

# remove the temporary file
rm -rf /tmp/cron.redmine

## End of Recurring Tasks Configuration

Now whenever the image is started the above init script will be executed and the required cron job will be installed.

Previously this image packaged a couple of plugins by default. Existing users would notice that those plugins are no longer available. If you want them back, follow these instructions:

cd /opt/redmine/data/plugins
wget http://goo.gl/iJcvCP -O - | sh

Please Note: this plugin install script is not maintained and you would need to fix it if required (especially broken links)

To uninstall plugins you need to first tell redmine about the plugin you need to uninstall. This is done via a rake task:

docker run --name=redmine -it --rm \
  -v /opt/redmine/data:/home/redmine/data \
  sameersbn/redmine:3.0.1 \
  app:rake redmine:plugins:migrate NAME=plugin_name VERSION=0

Once the rake task has been executed, the plugin should be removed from the /opt/redmine/data/plugins/ directory.

rm -rf /opt/redmine/data/plugins/plugin_name

Any configuration that you may have added in the /opt/redmine/data/plugins/init script for the plugin should also be removed.

For example, to remove the recurring tasks plugin:

docker run --name=redmine -it --rm \
  -v /opt/redmine/data:/home/redmine/data \
  sameersbn/redmine:3.0.1 \
  app:rake redmine:plugins:migrate NAME=recurring_tasks VERSION=0
rm -rf /opt/redmine/data/plugins/recurring_tasks

Now when the image is started the plugin will be gone.

Just like plugins, redmine allows users to install additional themes. You can find a list of available plugins in the Redmine Themes Directory

Themes should be installed in the themes directory at the data store. If you are following the readme verbatim, on the host this location would be /opt/redmine/data/themes.

mkdir -p /opt/redmine/data/themes

To install a theme, simply copy the theme assets to the themes directory. For example, to install the gitmike theme:

cd /opt/redmine/data/themes
git clone https://github.com/makotokw/redmine-theme-gitmike.git gitmike

With the theme installed you can start the docker image normally and the newly installed theme should be available for use.

Previously this image packaged a couple of themes by default. Existing users would notice that those themes are no longer available. If you want them back, follow these instructions:

cd /opt/redmine/data/themes
wget http://goo.gl/deKDpp -O - | sh

Please Note: this theme install script is not maintained and you would need to fix it if required (especially broken links)

To uninstall plugins you simply need to remove the theme from the /opt/redmine/data/themes/ directory and restart the image.

rm -rf /opt/redmine/data/themes/theme_name

For example, to remove the gitmike theme:

rm -rf /opt/redmine/data/themes/gitmike

Now when the image is started the theme will be not be available anymore.

For debugging and maintenance purposes you may want access the containers shell. If you are using docker version 1.3.0 or higher you can access a running containers shell using docker exec command.

docker exec -it redmine bash

If you are using an older version of docker, you can use the nsenter linux tool (part of the util-linux package) to access the container shell.

Some linux distros (e.g. ubuntu) use older versions of the util-linux which do not include the nsenter tool. To get around this @jpetazzo has created a nice docker image that allows you to install the nsenter utility and a helper script named docker-enter on these distros.

To install nsenter execute the following command on your host,

docker run --rm -v /usr/local/bin:/target jpetazzo/nsenter

Now you can access the container shell using the command

sudo docker-enter redmine

For more information refer https://github.com/jpetazzo/nsenter

To upgrade to newer redmine releases, simply follow this 4 step upgrade procedure.

Step 1: Update the docker image.

docker pull sameersbn/redmine:3.0.1

Step 2: Stop and remove the currently running image

docker stop redmine
docker rm redmine

Step 3: Backup the database in case something goes wrong.

mysqldump -h <mysql-server-ip> -uredmine -p --add-drop-table redmine_production > redmine.sql

Step 4: Start the image

docker run --name=redmine -d [OPTIONS] sameersbn/redmine:3.0.1

The app:rake command allows you to run redmine rake tasks. To run a rake task simply specify the task to be executed to the app:rake command. For example, if you want to send a test email to the admin user.

docker run --name=redmine -d [OPTIONS] \
  sameersbn/redmine:3.0.1 app:rake redmine:email:test[admin]

You can also use docker exec to run rake tasks on running redmine instance. For example,

docker exec -it redmine sudo -u redmine -H bundle exec rake redmine:email:test[admin] RAILS_ENV=production

Similarly, to remove uploaded files left unattached
