Compose image pulls fail from Docker Hub


(George Thiruvathukal) #1

I’m running into unexpected “incorrect username or password” errors pulling images from Docker Hub via docker-compose - despite the fact that I’m logged in.

For example, when trying to pull an image of Apache Zookeeper I see:

$ docker-compose pull zookeeper
Pulling zookeeper (wurstmeister/zookeeper:latest)...
ERROR: Get https://registry-1.docker.io/v2/wurstmeister/zookeeper/manifests/latest: unauthorized: incorrect username or password

Yet, I can pull without any problems using the Docker Engine CLI:

$ docker pull wurstmeister/zookeeper:latest
latest: Pulling from wurstmeister/zookeeper

Status: Image is up to date for wurstmeister/zookeeper:latest

Any thoughts as to what might fix the issue? This is happening on an Ubuntu Xenial machine in EC2 running the current stable versions of engine and compose (1.11.2/1.7.1) and the newest engine/compose release candidates (1.12.0-rc2/1.8.0-rc1).

In the logs I see this:

Specify the image namespace also.

docker-compose pull wurstmeister/zookeeper


(George Thiruvathukal) #3

Determining the image to pull isn’t the issue. If you take a look at the docker-compose snippet, it has correctly deduced the pull spec as wurstmeister/zookeeper:latest. Plus, docker-compose pull doesn’t take paths like docker pull does. Instead it takes zero or more service names which need to be in the docker-compose.yml project files. So, that part works.

The error message is about authentication (“incorrect username or password”). But authentication isn’t a problem with the core docker command. So, the question is really: Why is docker-compose not extracting authentication credentials from ~/.docker/config.json in the same way as the docker command?

Use docker login before docker-compose.
