AWS ElasticBeanstalk can't find Dockerfile

Question

I have the following directory layout

./www/index.php
Dockerfile
apache-config.conf

I then zip up the file and upload it onto Elastic Beanstalk, but I get the following error message:

[Instance: i-572d1ae8] Command failed on instance. Return code: 1 Output: Dockerfile and Dockerrun.aws.json are both missing, abort deployment. Hook /opt/elasticbeanstalk/hooks/appdeploy/pre/03build.sh failed. For more detail, check /var/log/eb-activity.log using console or EB CLI.

The log file contains the following message:

AppDeployPreHook/01unzip.sh] : Completed activity. Result:

caused by: Dockerfile and Dockerrun.aws.json are both missing, abort deployment (Executor::NonZeroExitStatus)

Why is my dockerfile not being read here? I can build the image and run it just fine without Elastic Beanstalk.

Answer 1

Sharing another possibility:

You were testing eb and you've just added your Dockerfile.

According to the doc

If git is installed, EB CLI uses the git archive command to create a .zip file from the contents of the most recent git commit command.

That's saying if your Dockerfile is not committed, it won't be zipped in therefore your instance can't find it.

Answer 2

Compress those stuff within your project folder(go into your project folder and zip everything), instead of zipping your project folder.

Answer 3

In my case there was a spelling mistake in Dockerfile name i.e DockerFile. Elastic Beanstalk is case sensitive.

Answer 4

I've come across this issue as well. It seems a Dockerrun.aws.json file is required as well. I believe that is because other files are included in the app. If you had only a Dockerfile and nothing else, it wouldn't be required.

Here's the documentation: http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/create_deploy_docker_image.html

You don't need to include parent directory in zip file. Suppose you want to zip ./www/index.php ,Dockerfile and apache-config.conf then,

zip dist.zip Dockerfile ./www/index.php apache-config.conf

The upload dist.zip. http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/using-features.deployment.source.html
