Public Docker Hub image: androidsdk, build setup is very slow

[Bogdan Heutschi]

I have setup pipelines to run some android tests and make some builds, but it seems the build setup step is very slow because of the docker image which should be cached by bitbucket, as I'm using androidsdk/android-31. Duration of the build setup step is 1.5-2 minutes.
One thing I've noticed is that if I tried the same setup in a different repo, with the same settings, the build setup time is < 20s. 
This is the code in bitbucket-pipelines: image: androidsdk/android-31
Do you have any suggestions for improving the build setup part?

Hi Bogdan and welcome to the community!

The build setup is doing additional things, like cloning the repo and downloading caches.

Did you watch a build of this repo as it was running, and was it showing to pull images for the majority of these 1.5-2 minutes?

If so, I would suggest creating a ticket with the support team so we can check the Pipelines build log and additional logs from our side, in order to troubleshoot.

If the setup is taking a lot of time on the clone part, and if you are running builds on branches or tags, you can try setting up in your bitbucket-pipelines.yml file the depth of the clone (which is 50 by default) to e.g. 1 if you only need the last commit for the builds:

If the long setup time has to do with caches, you could remove caches, but then your build may take a longer time downloading dependencies.

If the culprit seems to be pulling the Docker image, please create a ticket and provide the URL of a build with this issue and we will look into it. You can open a ticket via https://support.atlassian.com/contact/#/, in "What can we help you with?" select "Technical issues and bugs" and then Bitbucket Cloud as product.

Kind regards,
