artifactory-docker-examples: art-compose and hosting a docker repository not working together.

I have a 3 note setup (by using art-compose) and then hosting a docker repository in the resulting artifactory instance. I can login to the docker repo if I point the docker client directly at artifactory but if I try to use the nginx the authentication doesn’t seem to be making it across and it gives a strange error about v2 docker not supported.

I’m duplicating here but the original question is on slashdot.

• CentOS 7.3
• SELinux Disable
• All activity below is on the “host” machine, just using different IP addresses and ports.
• 10.15.53.21 is the host itself, this is where the art-compose was run.
• 172.19.0.3 is the bridged docker network for the artifactory container. nginx is 172.19.0.4.

We’re running artifactory 6.0.2 6.0.3 on-perm as a container (along with nginx and postgresql) as described in running artifactory as a docker instance.

I have set up the basic “docker” instance.

Locally on the same machine as the artifactory container:

# docker login localhost:8081
Username: test
Password: 
Login Succeeded

However, using the nginx port:

# export DOCKER_OPTS=" --insecure-registry docker-local.artifactory.company.com"
# echo password | docker login -u test --password-stdin artifactory.company.com
Error response from daemon: Get https://artifactory.company.com/v2/: unknown: Unsupported docker repository request for 'v2'

I also tried using ~/.docker/config.json with the auth information (base64) however it still giving me the same error.

artifactory.log shows:
