Compose: No auth config found

[benjyz]

In a docker machine, docker compose up has some auth config error, but its unclear what this error exactly is. Would nice to know which file this is looking for e.g.

$ docker-compose --verbose -p webapp up 
compose.config.config.find: Using configuration files: ./docker-compose.yml

docker.api.build._set_auth_headers: Looking for auth config
docker.api.build._set_auth_headers: No auth config in memory - loading from filesystem
docker.auth.auth.load_config: File doesn't exist
docker.api.build._set_auth_headers: No auth config found

That's not really an error, just a debug message. Are you encountering an authentication issue?

(The default location for auth config is ~/.docker/config.json, by the way.)

I got the same error. And my SSL verification is failing.
Even if I have config.json under C:\Users\user.docker\machine\machines\office and that already has all the cert paths set.
But docker compose is not taking the file. Any idea which certs is it referring here?

$ docker-compose --verbose up
compose.config.config.find: Using configuration files: .docker-compose.yml
docker.auth.find_config_file: Trying paths: ['C:\Users\user\.docker\config.json', 'C:\Users\user\.dockercfg']
docker.auth.find_config_file: No config file found

I had a similar error. Turned out i had some very large files in the docker-compose directory, not being included in the build or as volumes, but for some reason were causing it to hang. Once I removed the big files from the directory I was good to go.

@Swetad90 Are you sure that your user is in the docker group? I had the same issue when I forgot to 'adduser docker'

[campreb]

@bjholmes23 I had the exact same problem, fixed it with .dockerignore file 👍

I had this issue on a vultr deployment. The fix was to add my login id as a superuser
$ su - username Note: root login access was removed per security recommendations.

[bobsaget4lyfe]

I had this issue and it was resolved by reseting docker (turning it off and on again eh?)

Just open a terminal and enter this:

sudo service docker stop

Then just docker-compose like usually

• I am commenting as this is the top google result for my error.

(The default location for auth config is ~/.docker/config.json, by the way.)

How can I tell docker-compose to use a different location for this file?

I am using docker --config .docker inside my project, so docker-compose pull can't find authentication for the registry :(

[robertpro]

I fixed the issue by using DOCKER_CONFIG env var :)

DOCKER_CONFIG=.docker

I had a similar issue. Removing existing docker installation under all package names such as docker.io, docker, docker-engine and then reinstalling via apt-get docker.io solved it for me. I encountered a snap installation too, removed that one too.

In case anyone finds these helpful.

Removing existing installations
sudo apt-get remove docker docker-engine docker.io && apt-get purge docker docker-engine docker.io snap remove docker

Installing
sudo apt-get install docker.io
