Steps run on Octopus Server cannot use execution container that requires authentication

Prerequisites

• I have verified the problem exists in the latest version

• I have linked the original source of this report
• I have labelled the value stream (area/core, area/steps, ...)
• I have tagged the issue appropriately (kind/bug, kind/enhancement, feature/ ...)

The bug

When running a step on Octopus Server that uses an execution container docker image from an authenticated docker registry feed, the pull of the docker image to run the step in fails as the credentials aren't being passed to the package acquisition.

What I expected to happen

Steps that run on Octopus Server that use execution container images from authenticated feeds should run correctly.

Steps to reproduce

1. Create a private docker registry (e.g. gitlab)
2. Create a feed in Octopus for this registry, setting credentials (for gitlab this means using an access token)
3. Create a deployment process/runbook with a step that uses the default worker pool, and ensure that steps are allowed to run on Octopus Server.

The package acquisition will fail with access denied.

Screen capture

Affected versions

Octopus Server: 2020.6+

Workarounds

Run the step on a worker other the built-in Octopus Server worker. This can either be achieved by choosing a different worker pool, or disabling running on Octopus Server in Features and adding a specific worker to the default worker pool.

Running a step inside a container on a worker fails to auth at acquisition if image is hosted in GitLab registry with credentials

Release Note: Steps run on Octopus Server using execution containers will now authenticate to Docker registries correctly
