Custom templates: "No templates available."

[jangrewe]

Description

I'm using custom templates, and i can see that the request to /api/templates?key=containers returns my JSON, but the App Templates page just says "No templates available."

1. Set custom templates URL in settings
2. Go to App Templates page

Technical details:

• Portainer version: 1.13.2
• Target Docker version (the host/cluster you manage): 17.05.0-ce
• Platform (windows/linux): linux
• Command used to start Portainer: /usr/bin/docker run --name portainer -v "/var/run/docker.sock:/var/run/docker.sock" -v "/srv/portainer:/data" -p 6000:9000 portainer/portainer
• Target Swarm version (if applicable): -
• Browser: Firefox 53.0.3 64bit

It doesn't work with 1.13.1 and 1.13.0 either (when using --templates), but works fine with 1.12.4

@jangrewe could you share your JSON definitions?

Here's an abbreviated version which doesn't work:

[
  {
    "title": "Registry",
    "description": "Docker image registry",
    "logo": "https://faked.org/portainer/logos/registry.png",
    "image": "registry:latest",
    "ports": [
      "5000/tcp"
    ],
    "volumes": ["/var/lib/registry"]
  }
]

I had a similar issue when setting up custom templates.

For me adding the platform of the template to the JSON def seemed to fix this and my templates appeared without issue.

I've been able to reproduce this, indeed it seems that adding the platform field solves the problem. Will fix as this field should be optional.

Thanks, adding this field fixes it!

I'll keep this issue open as the platform field is documented as optional. Will be fixed in the next release.
