How to deploy a custom image?

In case you might want to deploy your own docker image of on our more of the servers the easiest way to do this is to deploy to a custom image to a public dockerhub. Currently the Helm files assume a public dockerhub repository. If you want it be private an key for authenticating with Dockerhub, or another registry should be added.

Most likely the custom image will be a version of the Frontend. So for instance in your values yaml overwrite the name of the image:

  # Deployment container is what is eventually run in the pod
    name: frontend
    # Docker image for this pod
    image: dockerhubname/imagename:tag

Run upgrade command:

helm upgrade  -f custom-values.yaml openstad . -n openstad

Push your image automatically to dockerhub

Every repository has a travis.yml file that would work automatically if a travis account was made dockerhub images are pushed. Both Dockerhub and Travis are free for open source project.

For instance the frontend has a .travis.yml file and de docker_publish script:

The publish script cert environment variables, these can be saved in repository settings in the Travis dashboard:


Auto deploy to cluster

It's possible, we do it for staging and release, to autodeploy to a Kubernetes cluster. See the docker_deploy file in the repository for this.

For deploy to work, the above variables are necessary and needed to add the kubernetes config file as a variable:


This is the kubeconfig generated encoded to a base64 string. For instance can be generated like this:

cat ${HOME}/.kube/config | base64 | pbcopy
