Red Hat Marketplace Requirements

A walk through of the changes required to enable your operator to work in an offline environment. This is also a technical requirement for Red Hat Marketplace.

Helm Operators

Update your Helm chart

Make sure your Helm chart only references the values file for images. Each image should be a single value (it can't be split into repository and tag, for example).

values.yaml

  containers:
  - name: {{ template "etcd.fullname" . }}
    image: "{{ .Values.image.image }}"
    imagePullPolicy: "{{ .Values.image.pullPolicy }}"

A great way to find all the parts of your helm chart that will need to be updated is to recursively search your project's template folder for "image:"

Here we see that the image is split into two values - repository and tag. This won't work because we need to have a single variable to override. Replace this line with a new, single variable:

Don't forget to add this new value to your Values.yaml file!

Override the image variable

In the watches.yaml file, add a field for overrideValues. It should contain each variable from the values.yaml file that corresponds to an image, and should be set to the environment variable you want to use.

NOTE: the variable name MUST follow the pattern RELATED_IMAGE_. There is code looking for that string in your operator.

Ansible Operators

Update your Ansible role

Make sure your role is using environment variables for images instead of hard-coded or regular variables. If it's not, update it:

Above you can see a reference to a image that's defined in the role's defaults/main.yaml file with an option to override it in values/main.yaml. Instead, use Ansible's lookup module to reference an environment variable and remove the variable from defaults/main.yaml to avoid confusion:

NOTE: Your environment variables need to follow the RELATED_IMAGE_ format, as there is code looking for this pattern.

Golang Operators

Make sure your code is using environment variables for any images your operator uses (any image except the operator itself).

All Operators (Helm, Ansible or Golang)

Define the environment variables

In the CSV and operator.yaml files, declare the variable and set to a default value.

You may now use external image registries if desired. You are not required to host all images in the Red Hat Connect internal image registry as was the previous practice for Red Hat Marketplace integration.

Entitled Registry

Other things to watch for

If you're in the habit of using the "latest" tag for your images, make sure you specify it. Because of how the automation is written that picks up these images, we need a tag to be present.

Make sure you aren't overwriting the image in your CR (and by extension in the alm-examples field of the CSV). The best way to handle this is removing the field from the CR/alm-examples.
