On my mac I use Rancher Desktop as my Docker Engine. Its open source and the Apache license means I can use it for free, personally and for work.
However, I ran into an issue when I tried to push an image to a private registry. The error message was:
The push refers to repository [MY_PRIVATE_REPOSITORY_URL/MY_CONTAINER]
Get "https://MY_PRIVATE_REPOSITORY/v2/": http: server gave HTTP response to HTTPS client
This is because the registry is using HTTP instead of HTTPS. This is a security risk, but I’m running this registry internally and I’m not too worried about it. I just want to push my image to a self-hosted registry.
jandubois and pavel-kalmykov on the Rancher Desktop Github discussion solved this issue for us. The solution is to add the insecure registry to the Docker Engine configuration. We do this is follows:
- Connect to the lima VM by running
$ LIMA_HOME="$HOME/Library/Application Support/rancher-desktop/lima" "/Applications/Rancher Desktop.app/Contents/Resources/resources/darwin/lima/bin/limactl" shell 0
- Edit the Docker Engine configuration by running
sudo vi /etc/docker/daemon.json - Add the insecure registry to the configuration file. For example:
{
"insecure-registries": ["MY_PRIVATE_REPOSITORY"]
}
- Save the file and restart the Docker Engine by running
sudo systemctl restart docker - [OPTIONAL] You might want to restart Rancher Desktop app as well.
Now you can push your images to your internally hosted registry. 🎉
Note: There is no way to persist this change between reboots
