Molgenis Jenkins Helm Chart

Jenkins master and slave cluster utilizing the Jenkins Kubernetes plugin. Wraps the kuberenetes jenkins chart, see documentation there!

Chart Details

This chart will do the following:

1 x Jenkins Master with port 8080 exposed on an external ClusterIP
All using Kubernetes Deployments

Installing the Chart

Usually, you'll be deploying this to the molgenis cluster. In the Rancher Catalog, add the latest version of this repository. In the molgenis cluster management page, choose the catalog, pick the molgenis-jenkins app from the catalog and deploy it.

Configuration

When deploying, you can paste values into the Rancher Answers to override the defaults in this chart. Array values can be added as {value, value, value}.

jenkins.Master.HostName=jenkins.molgenis.org
jenkins.Master.AdminPassword=pa$$word
jenkins.Persistence.Enabled=false
jenkins.Master.InstallPlugins={kubernetes:1.8.4, workflow-aggregator:2.5, workflow-job:2.21, credentials-binding:1.16, git:3.9.1, blueocean:1.6.2, github-oauth:0.29}
jenkins.Master.Security.UseGitHub=false
## if UseGitHub=true
jenkins.Master.Security.GitHub.ClientID=id
jenkins.Master.Security.GitHub.ClientSecret=S3cr3t
## end UseGitHub=true
PipelineSecrets.Env.PGPPassphrase=literal:S3cr3t

You can use all configuration values of the jenkins subchart.

Because we use jenkins as a sub-chart, you should prefix all value keys with jenkins!

GitHub Authentication delegation

You need to setup a MOLGENIS - Jenkins GitHub OAuth App. You can do this by accessing this url: add new OAuth app.

Secrets

When deployed, the chart creates a couple of kubernetes secrets that get used by jenkins.

You can override the values at deploy time but otherwise also configure them in Rancher or through kubectl.

Vault

The vault secret gets mounted in the vault pod so pipeline scripts can retrieve secrets from the vault.

Parameter	Description	Default
`secret.vault.token`	Token to log into the hashicorp vault	`xxxx`
`secret.vault.addr`	Address of the vault	`https:vault-operator.vault-operator.svc:8200`
`secret.vault.skipVerify`	Skip verification of the https connection	`1`

GitHub

Token used by Jenkins to authenticate on GitHub.

Parameter	Description	Default
`secret.gitHub.user`	username for the account	`molgenis-jenkins`
`secret.gitHub.token`	token for the account	`xxxx`

Gogs

Token used by Jenkins to authenticate on the RuG Webhosting Gogs.

Parameter	Description	Default
`secret.gogs.user`	username for the account	`p281392`
`secret.gogs.token`	token for the account	`xxxx`

Legacy:

Docker Hub

Account used in pipeline builds to push docker images to hub.docker.com.

They should read secret/gcc/account/dockerhub from vault instead!

Parameter	Description	Default
`secret.dockerHub.user`	username for the account	`molgenisci`
`secret.dockerHub.password`	password for the account	`xxxx`

Registry

Account used in pipeline builds to push docker images to registry.molgenis.org.

They should read secret/ops/account/nexus from vault instead!

Parameter	Description	Default
`secret.dockerHub.user`	username for the account	`admin`
`secret.dockerHub.password`	password for the account	`xxxx`

Command line use

Specify each parameter using the --set key=value[,key=value] argument to helm install.

Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,

$ helm install --name jenkins -f values.yaml molgenis-jenkins

Tip

: You can use the default values.yaml
