Generally when we are using CLI version of docker preferably in Linux (I use Arch BTW 👿) we have to enter pass key every time we are logging. To avoid that docker has provided a better way to save the credentials using credential-managers such as pass etc…,

Thanks to this Issue #102 we can now able to use pass (I prefer this since I am using it 😅) manager to save credentials and tell docker to login automatically using those.

Here is how we can set up:

1. Install pass - Pass: The Standard Unix Password Manager

sudo pacman -S pass

2. Download, extract, make executable, and move docker-credential-pass

wget https://github.com/docker/docker-credential-helpers/releases/download/v0.6.0/docker-credential-pass-v0.6.0-amd64.tar.gz && tar -xf docker-credential-pass-v0.6.0-amd64.tar.gz && chmod +x docker-credential-pass && sudo mv docker-credential-pass /usr/local/bin/

3. Create a new gpg2 key if you didn’t initialize pass yet!!

gpg2 --gen-key # Follow prompts from gpg2 utility

4. Initialize pass using the newly created key

pass init "<Your Name/Key>"

5. Add credsStore to your docker config. This can be done with sed if you don’t already have credStore added to your config, or you can manually add “credStore”:“pass” to the config.json.

sed -i '0,/{/s/{/{\n\t"credsStore": "pass",/' ~/.docker/config.json

6. Login to docker

docker login
