Open stoically opened 4 years ago

stoically commented 4 years ago

Terraform Version

Terraform v0.13.3

Affected Resource(s)

Terraform Configuration Files

data "docker_registry_image" "traefik" {
  name = "traefik:latest"
}

resource "docker_image" "traefik" {
  name          = data.docker_registry_image.traefik.name
  pull_triggers = [data.docker_registry_image.traefik.sha256_digest]
}

Expected Behavior

Should always silently upgrade the image / container

Actual Behavior

Error: Unable to remove Docker image: Error response from daemon: conflict: unable to delete 1a3f0281f41e (must be forced) - image is referenced in multiple repositories

Steps to Reproduce

Unfortunately not sure how to reproduce

Notes

Would it be safe to always force-remove images?

This occurred for me when I had multiple tags referring to the same image (e.g. nginx:latest and nginx:1.19.3). I worked around the issue by manually force-deleting the image with docker rmi -f [image id]. You should probably stop other containers using that specific image first though.
