[🚀 Feature]: Decreasing container layers

[efeozsoy]

Feature and motivation

In our current structure we had to use docker standalone image and latest version has 126 layers which has blocking us to add new things inside the container and taking a docker and push to aws ecr. It gives "rpc error: code = Unknown desc = failed to register layer: max depth exceeded what does it mean"

Usage example

we are currently planning to add other packages and even automation project inside this image but it blocks to proceed without changing the original project.

Several ARG and ENV lines could probably be grouped in single lines.

If without private info, can you share a sample that you are doing for testing purposes during development?

[efeozsoy]

we are using codebuild to push to ecr but for example you can make a simple automation project to inject it, also we are downloading python to run automation.

CMD ["/opt/bin/entry_point.sh"]

it is smth like that i created via chatgpt since i can not provide original codes

Ok, that's fine, I also found a command to count the number of layers

$ docker history -q selenium/standalone-chrome:nightly | wc -l
127

Just update something and check this number can be decreased

[VietND96]

Below is the image layers count after changing. It will be released in 4.20.0
