multiple docker args (environment variables with whitespace)

[amtrack]

How do you specify multiple docker args with dokku config:set?

Example:

-v /opt/foo/data:/app/data -v /opt/foo/logs:/app/logs

None of the following commands work for me

dokku config:set myapp DOCKER_ARGS=-v /opt/foo/data:/app/data -v /opt/foo/logs:/app/logs
dokku config:set myapp DOCKER_ARGS="-v /opt/foo/data:/app/data -v /opt/foo/logs:/app/logs"
dokku config:set myapp DOCKER_ARGS='-v /opt/foo/data:/app/data -v /opt/foo/logs:/app/logs'
dokku config:set myapp 'DOCKER_ARGS="-v /opt/foo/data:/app/data -v /opt/foo/logs:/app/logs"'

I'll look into it. However I strongly suggest you to use data volumes instead of manually passing insecure DOCKER_ARGS:

1. Method one: use docker storage:

sudo dokku volume:create my-app-data /app/data /app/logs
dokku volume:link my-app my-app-data

1. Method two: use host-based storage:

sudo dokku volume:create my-app-data /opt/foo/data:/app/data /opt/foo/logs:/app/logs
dokku volume:link my-app my-app-data

ok, thanks! will try that!

There is one more thing to mention: dokku-alt doesn't support DOCKER_ARGS specified in config:set as this is insecure (you can mess-up host system). User docker-args are supported by creating file (/home/dokku/app/DOCKER_ARGS) and pasting your custom arguments.

However, data-volumes are sanity checked and can be considered as secure enough :)

works like a charm! thanks!
