Missing support for proper healthchecks about mongo-cluster-docker HOT 4 CLOSED

nice

from mongo-cluster-docker.

Yep, you are right.

Because in official mongo images there isn't curl included https://github.com/docker-library/mongo/blob/master/3.4/Dockerfile .

This code is leftover from my early experimentation with custom mongo images. It's not required anymore. I've end up with going around this problem. Simply by trick with simply:

• adding dependency with depends_on:,
• not putting restart: always on mongo-xxx-setup

It's working like a charm.

But, you can easily add curl

docker run -it --rm  mongo bash

and then

apt-get update && apt-get install curl

or create own image with curl included (with Dockerfile).

l was planning rewrite it with docker HEALTHCHECK support, so pull requests are welcome.

from mongo-cluster-docker.

Added healthcheck using plain mongo without any need for curl.

echo "Waiting for startup.."
until mongo --host ${mongodb1}:${port} --eval 'quit(db.runCommand({ ping: 1 }).ok ? 0 : 2)' &>/dev/null; do
  printf '.'
  sleep 1
done
