How to use --settings option when starting the container?

[viveksd87]

We have built a meteor app that requires --settings to be specified for using S3 bucket information.

To run on our local we typically use the command:
meteor run --settings settings.json

Even to deploy on meteor.com we would say:
meteor deploy --settings settings.json

How do we specify the settings parameter when using the image to deploy it within a container?

May be this:
docker run ... -e METEOR_SETTINGS="$(cat ~/myfolder/settings.json)"

[schandrac]

pass an environment variable. I pass it via environment option in docker-compose file

• METEOR_SETTINGS={"public":{"portal_url":"my-url-here"}}

You can create a file (let's call it .dockerenv) with your env vars listed like this…

ROOT_URL=http://localhost
MONGO_URL=mongodb://123.456.789.123:27017,123.456.789.124:27017/flow?replicaSet=rs0&readPreference=primaryPreferred&w=majority
MONGO_OPLOG_URL=mongodb://oplogger:MYPASSWORD@123.456.789.123:27017,123.456.789.124:27017/local?authSource=admin
MAIL_URL=smtp://postmaster%40myname.mailgun.org:MYPASSWORD@smtp.mailgun.org:2525

…and then run docker run using the --env-file flag pointing to the file like this: docker run --env-file .dockerenv

Yey! That's pretty close to the classic meteor settings.json file!
