When creating our Elastic Beanstalk environment in the next lecture, we need to select Docker running on 64bit Amazon Linux 2 and make a few changes to our project:
This new AWS platform will conflict with the project we have built since it will look for a docker.compose.yml file to build from by default instead of a Dockerfile.
There are one of two ways to resolve this.
#1 - Rename the Compose config file:
Rename the docker-compose.yml file to docker-compose-dev.yml. Going forward you will need to pass a flag to specify which compose file you want to build and run from: docker-compose -f docker-compose-dev.yml up docker-compose -f docker-compose-dev.yml up --build docker-compose -f docker-compose-dev.yml down
No other changes will be necessary. Since a docker-compose.yml file does not exist, AWS EBS will instead build the Dockerfile as shown in the lecture videos.
#2 - Create a production only Compose config file:
Rename the docker-compose.yml file to docker-compose-dev.yml. Going forward you will need to pass a flag to specify which compose file you want to build and run from: docker-compose -f docker-compose-dev.yml up docker-compose -f docker-compose-dev.yml up --build docker-compose -f docker-compose-dev.yml down
Then, create a new docker-compose.yml file in the root of the project and paste the following:
version: '3' services: web: build: context: . dockerfile: Dockerfile ports: - '80:80' AWS EBS will see a file named docker-compose.yml and use it to build the single container application.
