Description
Failed to create container from the image with uppercase name.

Steps to reproduce the issue:

  1. Navigate from menu Containers -> click Add Container
  2. Input an image name with uppercase letter, for example "myapp:RC1", and disable "Always pull image before creating" -> click Create
  3. Error message prompt: "No such image: myapp:rc1"
  4. Expected result: portainer should create a container from "myapp:RC1" image.

Technical details:

  • Portainer version: 1.11.0
  • Portainer Docker image tag (latest/arm/windows...): latest
  • Target Docker version (the host/cluster you manage): 1.11.1 and 1.12.3
  • Target Swarm version (if applicable): NA
  • Platform (windows/linux): Ubuntu 14.04 LTS
  • Browser: Chrome 42

Workaround: add a full lowercase tag to the image.

Maybe this causes: function prepareImageConfig in app/components/createContainer/createContainerController.js always force image config to lower case.

(but i have no env to verify)

Indeed, this comes from: https://github.com/portainer/portainer/blob/develop/app/components/createContainer/createContainerController.js#L144

This issue will also be present in:

Only the image name should be lowercased, not the tag.

Image/tag constraints can be found here: https://docs.docker.com/engine/reference/commandline/tag/
