In one of the CI workflows we have at work, I was trying to run a Docker image with a custom run command. However, since this was on a CI machine, it wasn’t able to find a valid Consul/Vault server and would simply keep retrying connecting to the server. As a result, the application just wouldn’t start…
The logs looked something like this:
RL: GET https://vault:8200/v1/_vault/non-existing
Code: 403. Errors:
* permission denied (retry attempt 1 after "250ms")
2018/03/22 09:52:17.387832 [ERR] (view) vault.read(_vault/non-existing): vault.read(_vault/non-existing): Error making API request.
URL: GET https://vault:8200/v1/_vault/non-existing
Code: 403. Errors:
* permission denied (exceeded maximum retries)
2018/03/22 09:52:17.387918 [ERR] (runner) watcher reported error: vault.read(_vault/non-existing): vault.read(_vault/non-existing): Error making API request.There’s an open issue on the envconsul repo about the same.
It turns out that an easy way to fix this is to provide a Docker Entrypoint argument to the run command. In my case, passing --entrypoint [] did the trick.
