Deploy NodeJS Express API to AWS

Question

I used CodeFresh to build my Docker Image and push to AWS ECR.

I check my ECR, I can see the pushed there successfully.

I SSH into my EC2, I don't see any content there.

Answer 1

First thing

By doing ls does not mean it will show the docker image.

If the docker images pull successfully then check it using below command.

docker images

This will print all the images that are running in this ec2 container instance. something like 56789.dkr.ecr.us-east-2.amazonaws.com/bheng-api:latest.

As for debugging is a concern you need to check is your docker container is running.

docker ps

This will print running container.

copy the id of the container and run this command.

docker exec -it {container_id} bash|ash

docker logs

docker logs  {container_id}

You can also check how images is working by assigning role to your ece container instace and run the following command.

docker run -it --rm -p 80:80 56789.dkr.ecr.us-east-2.amazonaws.com/bheng-api:latest

Again I will mention the steps

1. create ECR and push ur docker image
2. create Task definition
3. create service that runs the instance of that task definition. with out service there will be nothing like container or docker image. once u create service you will se docker image in your ec2 instance.

You can also view tasks events using AWS console under ECS -> cluster -> service -> tasks

If some thing went wrong you will see in the events like

If every thing ok then

Complete image
