Adding the --insecure-registry
flag has been a bit of a pain for me. I’d ssh into the boot2docker machine and edit the file before restarting docker on the VM. Unfortunately every time the docker machine restarted I would lose the configuration and have to perform the same steps again.
Fortunately, I discovered the configuration files for the docker-machines and that it allows you to specify insecure registries by configuration.
Do the following to enable your insecure registry once and for all:
Edit the configuration file for your docker-machine (default in this case):
vi ~/.docker/machine/machines/default/config.json
Locate the `InsecureRegistry` key and simply append your insecure registry to the array.
"HostOptions": { "Driver": "", "Memory": 0, "Disk": 0, "EngineOptions": { "ArbitraryFlags": [], "Dns": null, "GraphDir": "", "Env": [], "Ipv6": false, "InsecureRegistry": [ "insecure-registry.mydomain.com" ],
Then re-provision the machine with:
docker-machine provision default
Note: re-provisioning will likely lose any manual changes you made to the VM.
