Dockerfile inconsistent build vs local

We are using docker and ECS/ECR on AWS to deploy.

I have a shell script that CircleCI is meant to execute. If I run it locally it runs fine and the image deploys smoothly to Amazon. However if I do the same thing via CircleCI the docker container exits and has this error

Below is our docker file and the shell script - the only thing removed are some sensitive variables. Docker should consistently build across any machine so I am at a loss as to why this is occurring.

Note - if I SSH into the box and manually run the file it RUNS FINE. It is only erroring when CircleCI is executing on deploy script via circle.yml

Relevant circle.yml snippet

        branch: dev-aws2
            - ./

Are you selecting a Ruby version in your circle.yml file? If not, could you please do so? (There is an example here.) This will make sure that the Ruby environment is set up properly.

Also, is bundle install step run in your build? In which section of the build does it get executed? Thanks.

bundle install is run in the build and ruby 2 is selected in circle.yml

The fact that the script works fine via ssh indicates that timing is involved with the error somehow. I still don’t understand how timing is involved, but can you add sleep 60 right before running the script?

To close this out there was a red-herring in the debugging.

We were trying to add the app files without repulling from git. As a result we were adding the modfiied version of the files that CircleCI uses for tests (For those unaware CircleCI modifies the database.yml and a few other bits) the bundle install CircleCI ran also threw off our build.

To resolve once tests pass in our deployment phase we cd /tmp and re clone the repo from the appropriate branch and then run the docker build command there.
