Overview#

Docker is handy for machine learning development. After installing it though, commands like docker ps often fail with a permission error. Since I keep forgetting the steps to run docker without sudo, I’m leaving them here as a personal note.

Prerequisites#

• Docker is already installed

Steps#

1
# Create the docker group if it doesn't exist
2
sudo groupadd docker
3

4
# Add the current user to the docker group
5
sudo gpasswd -a $USER docker
6

7
# Restart the docker daemon (CentOS 7 case)
8
sudo systemctl restart docker
9

10
# Log out and log back in to apply the changes
11
exit

Wrap up#

Make docker easier to use and enjoy your dev life!
