-## Deployment
+# Janus
+> A Dockerized Jenkins CI-CD system for Apella
 
-To deploy the Jenkins server use the commands:
-```bash
+Janus is a Docker image that contains an instance of Jenkins with all the necessary configuration built into it for handling the CI-CD of Apella.
+
+## Prerequisites
+
+Only needs a working installation of Docker. 
+
+## Installation
+
+The credentials of the default admin user created are passed to Jenkins using docker secrets. The files containing the username and password to be used can be found at the paths `./jenkins/secrets/user` and `./jenkins/secrets/pass` respectively. Edit the files to change the default username and password.
+
+Then run:
+
+```sh
 make build
 make run
 ```
 
-To get the administrator password created use the command:
-```bash
-docker exec jenkins_master_1 cat /var/jenkins_home/secrets/initialAdminPassword
+During the Docker image build, a key-pair is created for usage with Gitlab. Get the public ssh key using:
+
+```sh
+./utility-scripts/printJenkinsGitlabSSHPublicKey.sh
 ```
 
-Remove **all** images:
-```bash
-docker images -q | xargs docker rmi -f
-```
+Then, on Gitlab, add the public key to the deploy keys of the project.
+
+Jenkins also needs an access token from Gitlab to update build statuses. Create an access token and add it to Jenkins under Global Credentials.
+
+Lastly a Webhook must be added to Gitlab, pointing to the Jenkins project. On Gitlab, navigate to the Webhooks menu in the Settings of the project and add a new webhook pointing to `https://jenkins.apella.tk/project/staging-apella-multibranch-pipeline`.
