Docker images unable to find circleci user



Hi friends,

A ruby-based build task has begun failing at the ‘Spin Up Environment’ step. It seems to correlate with some rolling updates to the docker images occurring right now. This is the output of the step:

Build-agent version 0.1.1073-1f69f340 (2018-11-20T18:07:03+0000)

Error response from daemon: linux spec user: unable to find user circleci: no matching entries in passwd file

The updates can be seen here in the Docker Hub:

I tried changing to a different image just to throw a random dart at the problem but it still failed.

Thanks for any help.

We’re seeing this error as well, on the circleci/ruby:2.3.8-node docker image.

We have a different project using circleci/ruby:2.5.1-node-browsers that doesn’t seem to be affected, but that might just be caching at work.


I’m seeing the exact same thing with the circleci/golang:1.11.2-node image.


Same issue with openjdk images


Biting us right now too - this is frustrating…


We’ve got a workaround - pin to the last working docker image sha256. You can grab that from the “spin up environment” step of the last successful build, then just include is in your circle config.

This is what we’re using for ruby-2.3.8-node-browsers:
image: circleci/ruby@sha256:be06794b34768076ae9d8f94f8d7f3930d31ef866fbe3e6d53a4875d3ec245c0


We’re using Ruby 2.5.3, but seeing it when we start the redis image (which apparently happens before rails)

Error response from daemon: linux spec user: unable to find user circleci: no matching entries in passwd file


Same here. Reproducible on my Mac:

✗ docker run circleci/python:2.7.15-node
docker: Error response from daemon: linux spec user: unable to find user circleci: no matching entries in passwd file.
ERRO[0000] error waiting for container: context canceled


We have the same problem as well, pulling from circleci/ruby:2.5.3-node (circleci/ruby@sha256:937822264394cc653444e15a65595624e358c3a8a03ecc66356af35c042b5914) and circleci/postgres:9.6-alpine-ram (circleci/postgres@sha256:6bde827b91b15d6250882ca6610f43570e89ef3a5db842b052c2201415cc7554).


Seeing this too. I can confirm that specifying the sha in config.yml for the ruby image (I got mine from the output of my last successful CI run) mitigates the issue for now.


CircleCI support recommended the sha pinning as a workaround, and said they’re working on it.

Image circleci/php:5.6-apache-node doesn't work anymore

Update: The issue has been identified and fix applied. New images are already being published, but it will take a few hours to get through them all.

Thank you all for reporting.

Original Status

This is not solved, but I am locking the post while we investigate.

We are aware of the issue impacting many Docker images where the user is missing, causing builds to fail. The issue has been escalated to our engineers who are working the problem currently.


As a workaround we do suggest pinning to the specific sha used on a previous successful build. You can find this in the “Spin Up Environment” step of a previous successful job.


Same with circleci/python:2-node



This issue has been fully resolved at this time.
