Configure customPullSecret in DynaKube

To define a custom pull secret

Expected behavior

When a DynaKube custom resource is applied, a pull-secret called <dynakube-name>-pull-secret is generated by default. This pull-secret is used by:

If you set the customPullSecret field in DynaKube, no pull secret is generated. To pull an image directly from the environment registry, the secret that the customPullSecret points to needs to have auth credentials for the environment registry.

Example auth entry for the environment registry in .dockerconfig.json

1.dockerconfigjson: {
2    "auths": {
3        "<tenant-registry>": {
4            "username": "<tenant-uid>",
5            "password": "<dynatrace-operator-token>",
6            "auth": "<tenant-uid>:<dynatrace-operator-token>" # <- base64 encoded; should be the one used by DynaKube.
7         };
8       ....
9     },
10}
