An Open Source Node.js Cloud-Operator for Development supported by consol with ๐.
This project is "work in progress" ๐ง. Many features are still missing. Same for security. โ Don't use this version in production.
You and your team ๐ฅ
- โ is developing a web application in the โ cloud?
- โ use branches for parallel ๐ feature development?
... great, maybe PLICITY can help you! ๐จโโ๏ธ
The idea is very simple ๐ก
- ๐ PLICITY will watch your Git repository
- ๐ง every time a branch is created, it will trigger a hook
- ๐ฎ same for deleting or updating a branch
A simple idea needs simple implementation โ:
- ๐ the operator is Node.js script in your project
- ๐ถ it will start everything and implement the hooks
- ๐ hooks are simple JS callbacks
operator.start({
onCreateBranch: setup, // a new git branch is created
onChangeBranchHead: startBuild, // push to a branch
onDeleteBranch: deleteAll, // delete a remote branch
onServerBuild: startBuild // press "Build" in the Operator UI
});
onCreateBranch
When a new git branch is created, we could oc process -f ...yml | oc apply -f -
a template which will deploy everything needed for the application? It should create an ImageStream
, BuildConfig
, ..., maybe also a new isolated Database and of course a Route
because we want to access it.
async function setup(event) {
await oc.project(event.args.openshiftProject);
await oc.applyTemplate(`${__dirname}/setup.yml`, {
GITLAB_REPOSITORY_URL: event.gitlabRepositoryUrl, // needed for BuildConfig
BRANCH_NAME_NORMALIZED: event.branchNormalized, // needed for BuildConfig
NAME: event.args.name // used as prefix for all resource names and labels
});
}
onChangeBranchHead, onServerBuild
When a branch has a new commit or someone presses "Build" in the Operator UI, we simply want to start the build.
async function startBuild(event) {
await oc.project(event.args.openshiftProject);
await oc.startBuild(`${event.args.name}-${event.branchNormalized}`, {commit: event.commit});
}
onDeleteBranch
When a branch is deleted, we want to delete everything we set up in setup
. We use labels, that we can delete everything with one command.
async function deleteAll(event) {
await oc.project(event.args.openshiftProject);
await oc.deleteAll(`app.plicity.io/branch=${event.args.name}-${event.branchNormalized}`);
}
Conclusion
Of course you're free to do more in the hooks, like running smoke ๐ฌ or โ integration tests or create ๐ซ notifications on your Slack channel.
You run the operator. You implement the hooks. Everything is under your control. Create your very best build pipeline for development. PLICITY will โฅ to support you and your team with ๐ development, ๐งช testing and finally โต ship faster.
Now give it a try and please give feedback ๐ฌ.
Before using it, please also check Security section.
The target folder has to exist and should be empty.
npm init @plicity <target dir>
git add -A
git commit -m 'add plicity'
git push
Go into your target directory and open /plicity/.env
.
You can get url and token by copying your login command
It should look like this:
oc login https://openshift.mycompany.org:8443 --token=abcdefghijklmnopqrstuvwxyz0123456789
Use an openshift project which is already created for your app.
PLICITY_OPENSHIFT_URL=https://openshift.mycompany.org:8443
PLICITY_OPENSHIFT_TOKEN=abcdefghijklmnopqrstuvwxyz0123456789
PLICITY_OPENSHIFT_PROJECT=plicity-test
Note: Gitlab project needs to be public. Also see Security section.
Just the Gitlab host. Not the URL to the repository.
PLICITY_GITLAB_HOST=https://gitlab.mycompany.org
Go to your Gitlab Project and copy the Project ID
.
PLICITY_GITLAB_PROJECT_ID=1147
Go to Settings
.
Go to Access Tokens
.
Create Access Token.
PLICITY_GITLAB_TOKEN=abcdefghijklmnop
Name of the Operator and used as prefix $name-...
for all OpenShift resources. It has to only contain valid characters or it will crash.
PLICITY_NAME=pli
Just for local development of your Operator.
Valid log level according to pino logger. In OpenShift it will run info
.
PLICITY_LOG_LEVEL=debug
Just for local development of your Operator.
Log output has json format. Make it human-readable setting this to true
. In OpenShift it will output json.
PLICITY_LOG_PRETTY=true

Check OpenShift to see Operator build.
When Operator POD is up and running all branches will be deployed.
If you want to use your own registry:
npm init @plicity <target dir> \
--npm-registry=http://registry.mycompany.org \
--npm-strict-ssl=false
Good things first ๐ฌ:
- 100% On-Premise in your Private or Public Cloud.
- No OpenShift cluster admin rights needed.
- Your OpenShift token is not exposed. The Operator will run with a special
ServiceAccount
with aRoleBinding
allowed to control your project. Your token is just used for the initial setup or if you want to run the Operator local, e.g. updating it.
Need of improvement ๐ค:
- Gitlab project needs to be public. Yet no authentication implemented.
- We give full Gitlab access to the Operator. Assumption is that the only API call we need at current is to add and remove the badge to the Gitlab project. This may change when implementing authentication for OpenShift for Gitlab.
- Your Gitlab Token is exposed as OpenShift secret. Everyone with access to your project can use that Gitlab token.
Grey zone ๐คซ:
- download OpenShift client
oc
from https://github.com/openshift/origin/releases/download/v3.11.0/openshift-origin-client-tools-v3.11.0-0cbc58b-linux-64bit.tar.gz. Customizable alternative location to be implemented.
alphabetical order
- Will not work on Windows and probably not on MacOS
- Only OpenShift compatible with oc v3.11.0 and Gitlab supported
