Where should I set the '--insecure-registry' flag on Mac OS?

Question

I am using OS X 10.10. When trying to communicate with our team's private docker registry, it keeps giving me errors like this:

Error: Invalid registry endpoint https://registry.xxx.xxx/v1/: Get https://registry.af-sys.com/v1/_ping: dial tcp xx.xxx.xxx.xxx:xxx: i/o timeout. If this private registry supports only HTTP or HTTPS with an unknown CA certificate, please add --insecure-registry... 

On Ubuntu system this error can be resolved by adding DOCKER_OPTS into the /etc/default/docker configuration file like this:

DOCKER_OPTS="$DOCKER_OPTS --insecure-registry myregistry:5000" 

Does Mac OS have a similar configuration file where I can add the DOCKER_OPTS option?

Answer 1

I was looking for a way to set --insecure-registry in Docker for Mac. Turned out to be simpler than what I first thought...

In the Docker Desktop application :

1. click on the Settings icon
2. select Docker Engine menu entry
3. add your insecure registries

Don't forget to Apply & Restart and you're ready to go.

You have to set it to Docker Machine's / Boot2Docker profile file: docker-machine ssh <machine name>

/var/lib/boot2docker/profile

EXTRA_ARGS=' --label provider=virtualbox --insecure-registry myregistry:5000  ' 

And then restart Docker service.

sudo /etc/init.d/docker restart
