How can I preseed my credentials to docker login command within a script ?
I'm using a bash script that basically automates the whole process of setting up my custom VMs etc, but when I need to login to docker within the script to pull the images, I get the following error:
Username: FATA[0000] inappropriate ioctl for device
The command I was using is the following:
( echo "xxx"; echo "yyy"; echo "zzz" ) | docker login docker.somesite.org
Is this possible to achieve without using and coping over an existing .dockercfg file and how,
Many thanks.
There's now an officially-documented way to do this:
cat ~/my_password.txt | docker login --username foo --password-stdin
You can pass all the arguments on the command-line:
docker login --username=$DOCKER_USER --password=$DOCKER_PASS $DOCKER_HOST
If you don't specify DOCKER_HOST, you'll get the main Docker repo. If you leave out any of the arguments, you'll be prompted for that argument.
The same path as just above, except that you need to also pass an --email flag. The contents of this are not actually checked, so anything is fine:
docker login --username=$DOCKER_USER --password=$DOCKER_PASS $DOCKER_HOST --email whale@docker.com
