I'm trying to set up amazon-ecr-credential-helper and I followed the instructions from here: GitHub Repo I cloned the source and compiled it manually by running

make docker

then copied the binary to /usr/local/bin. I added the line "credsStore": "ecr-login" to the docker daemon config file and when I attempt to do a

sudo service docker restart

it fails to restart. When I check the log file I see the line

the following directives don't match any configuration option: credsStore

CodePudding user response：

You're mixing up the docker engine's /etc/docker/daemon.json with the docker cli's $HOME/.docker/config.json. These are two different files with different contents and syntaxes.

Remove the line from the daemon.json and add it to the users config.json. There shouldn't have been a need to stop docker to configure this.
