-----------------------------------------
Summary: Incompatibility between Mesos and Docker - (not) picking
up ~/.docker/config.json
Key: MESOS-4725
URL: https://issues.apache.org/jira/browse/MESOS-4725
Project: Mesos
Issue Type: Bug
Reporter: Tomasz Mieszkowski
Having Mesos 0.23.1 and Docker 1.7.1, I can put my auth token for my private
registry (Artifactory) into {{/root/.docker/config.json}} on every slave node,
and when I'm deploying my dockerized app to Mesos via Marathon it works fine
(i.e., this auth token is picked up by Docker and images are pulled
successfully).
But when I use Mesos (1) and Docker >= 1.8.3 (2), this mechanism doesn't work
anymore (i.e., for some reason {{/root/.docker/config.json}} is ignored, and
therefore Docker is unable to pull images from the same location as above).
What makes it interesting, is the fact that when I run the same command as
Mesos (3) from the root's shell, directly on any slave node, it works as
expected (i.e., images are pulled successfully), so this clearly is not
Docker's fault.
Any ideas what it may be..?
(1) - Tested with Mesos 0.23.1, 0.24.1, 0.25.0, 0.26.0 and 0.27.0.
(2) - Tested with Docker 1.7.1, 1.8.3 and 1.9.1.
(3) - {{docker -H unix:///var/run/docker.sock pull
my.private_registry.com/xxx/my_image:latest}}
