ettore26 / wait-for-command Goto Github PK

Using a combination of wait-for-command.sh and another command as the command: directive in a docker-compose file with an Alpine based image yields wait-for-command trying to use && as an argument.

command: wait-for-command.sh -c 'nc -z db 3306' && $command

wait-for-command.sh tries to utilize the && and the script breaks, uncertain if this is a shell or script issue.
Sorry I don't have an exact log on hand at the moment, if necessary will reproduce.

Current workaround: (installing bash already, so using it)
command: bash -c "sh -c \"./wait-for-command.sh -t 120 -c 'nc -z db 3306'\" && $command"

I'd love to see the behaviour similar to https://github.com/vishnubob/wait-for-it => enabling endless wait (for example for timeout == 0)

my command of interest:

docker inspect -f "{{.State.Health.Status}}" p6spy_postgresql_1 | grep -qw healthy

once running without wait-for-command.sh I see:

docker inspect -f "{{.State.Health.Status}}" p6spy_postgresql_1 | grep -qw healthy && echo $?
0

So should be all fine, but using wait-for-command.sh I see:

/tmp/wait-for-command.sh -t 1 -c 'docker inspect -f "{{.State.Health.Status}}" p6spy_postgresql_1 | grep -qw healthy'
wait-for-command.sh failed after 1 second(s).
cmd:                 docker inspect -f "{{.State.Health.Status}}" p6spy_postgresql_1 | grep -qw healthy
target exit status:  0
exited status:       125
