Regarding Dockerfile

[khatrigopal]

Hi

I have 3 working environments DEV/QA/STG and and i am using nodejs application. Now i want to create a Dockerfile for all the environment, but challenges are:

1. Create a generic Dockerfile for all the env, but all the env. are using diff-differ values
2. Env Values are:
   COOKIE_PASSWORD
   HEAD_UNIT_USERNAME
   HEAD_UNIT_PASSWORD
   PG_DB
   PG_HOST
   PG_PORT
   PG_USERNAME
   PG_PASSWORD
   PORT
   WS_ACCESS_KEY
   AWS_SECRET_ACCESS_KEY
   AWS_REGION
   AWS_S3_BUCKET
   AWS_SQS_CAMPAIGNS_QUEUE_URL
   AWS_SQS_VEHICLES_QUEUE_URL
   PQSS_ENABLED=true
   AWS_SQS_NOTIFICATION_QUEUE_URL
   API_KEY_ENABLED
   API_KEY_ID

These values are differ for all DEV/QA/STG.
so How can i create a generic Dockerfile and use these env for particular env.

Please resolve it.

create three different env-files for DEV QA UAT
using docker-compose call env-files

You can pass those variables in your command line while running your container with help --env and you change variables which are under ENV instruction but not ARG

Try this link, you get an clear idea:
docker/compose#6170
