Here is what the entry looks like from the terminal. sudo nano /Users//.ssh/config Host ubuntu HostName user IdentityFile ~/.ssh/ubuntu_rsa ssh-copy-id -i /Users//.ssh/ubuntu_rsa your ssh hosts file and add the following with the variables substituted for what they actually are. Then you will want to copy that key to the remote ubuntu server using the ssh-copy-id command. Hit enter through all the prompts to skip adding a password (unless you feel compelled to have a password for this). The following command will let you do that. Configure SSH from your Macįirst step to getting ssh setup is generating an ssh key. sudo nano /etc/nf # Add this line to the end vm.max_map_count=262144Īfter doing that run the sudo sysctl -system command will reload your shell with the configuration changes we made.
It sets how much virtual memory your containers are allowed to request.

By the way, I’ve spent the best part of an hour trying to find how to do this and combing through the history of why docker-machine ssh no longer works. Not all containers will need this set but if you do need it, figuring out that it’s missing can be tricky. FWIW, my use case is that I want to be able to use dmesg from containers, but it first requires unrestricting it with sysctl kernel.dmesgrestrict0 in the host. I would recommend editing /etc/nf and adding the following line to the very end. sudo addgroup -system docker sudo adduser $USER docker newgrp docker sudo snap disable docker sudo snap enable docker This way you can run docker commands without being a sudo’er and allows us to remotely connect to the docker daemon.

sudo snap install dockerĪfter install installing the docker snap it’s important to also add your user to the docker group. For getting docker installed I would recommend using the snap.
