CircleCi build failed

Build Environment

Hi,
Sometimes i get build failed in CircleCi for first time, and if i rebuild the test it works well, i don’t know what is the problem!

Build failed message

    #!/bin/bash -eo pipefail
set -x
docker-compose -f docker-compose.ci.yml up -d prod
docker-compose -f docker-compose.ci.yml exec prod curl --retry 10 --retry-delay 5 -v http://127.0.0.1:8000
+ docker-compose -f docker-compose.ci.yml up -d prod

Any idea about this topic please?

Yep, the problem is here:

You’re not waiting for this server long enough before you’re trying to use it. There’s a race condition between full server init and your tests, and on the random occasions the server starts up first, things will pass.

If that’s not sufficient help, readers would probably need to see your Circle config, and perhaps your docker-compose.yml as well, to see where a wait would need to be added. However, I suggest you give it a go first.

I think sleep command should fix this problem

Yes @halfer sleep command fix this issue,

This is my config before

 - run:
          name: Run tests
          command: |
            set -x
            docker-compose -f docker-compose.ci.yml up -d prod
            docker-compose -f docker-compose.ci.yml exec prod curl --retry 10 --retry-delay 5 -v http://127.0.0.1:8000

Config after

 - run:
          name: Run tests
          command: |
            set -x
            docker-compose -f docker-compose.ci.yml up -d prod
            sleep 30
            docker-compose -f docker-compose.ci.yml exec prod curl --retry 10 --retry-delay 5 -v http://127.0.0.1:8000

Thanks @halfer +1

Great stuff. You’ll probably find a smaller sleep is fine - usually under 10 seconds will do it, but it depends what’s in the DC config.

Yes, it depends of docker-compose config
