Could not gracefully run server

[nblum]

I tried to setup based on the docker image:

docker run -e "DATABASE_URL=memory" -d --name my-hydra -p 4444:4444 oryd/hydra

runnying hydra host output is

Is there any log to figure out what went wrong?

check if port 4444 blocked somehow

I tried to start container without port binding (to prevent used ports on the host system) docker run -e "DATABASE_URL=memory" -d --name my-hydra oryd/hydra.

netstat -tulpn (inside the container) shows:

Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name    
tcp        0      0 :::4444                 :::*                    LISTEN      7/hydra

I think this is from the entrypoint which runs the hydra host command initially

#514 will show a more verbose error message which will hopefully help resolve this.

[aeneasr]

#514 is now merged and released under latest master and 0.9.2 - make soure you're actually pulling the latest version in docker with oryd/hydra:0.9.2. Building the docker image usually takes ~20 minutes.

perfect, i will try again

[nblum]

ok as you expected the error message is: FATA[0014] Could not gracefully run server error="listen tcp :4444: bind: address already in use"

Should it be possible to run hydra host inside the docker container again?

[aeneasr]

You can try to kill off all containers with docker kill $(docker ps -q) and then re-run this container, but since this isn't a hydra issue I'm closing this. You can also ask on our Gitter chat channel for help!
