docker-compose up超时与UnixHTTPConnectionPool

Question

In our Jenkins agents we are running about several (around 20) tests whose setup involves running docker-compose up for a "big" number of services/containers (around 14).

From time to time, I'll get the following error:

ERROR: for testdb-data  UnixHTTPConnectionPool(host='localhost', port=None): Read timed out. (read timeout=60)
An HTTP request took too long to complete. Retry with --verbose to obtain debug information.
If you encounter this issue regularly because of slow network conditions, consider setting COMPOSE_HTTP_TIMEOUT to a higher value (current value: 60).

Haven't been able to reproduce this consistently. And I'm still trying to figure out whether or not there is a correlation with our agent's resources being at full use.

docker -v is 1.10.1 and docker-compose -v is 1.13.1.

Any ideas about what this may be related to?

Answer 1

Restarting docker service:

sudo systemctl restart docker

and setting DOCKER_CLIENT_TIMEOUT and COMPOSE_HTTP_TIMEOUT environment variables:

export DOCKER_CLIENT_TIMEOUT=120
export COMPOSE_HTTP_TIMEOUT=120

are two workarounds for now. But the issues are still open in docker compose github:
