What are we removing from project.pbxproj? Also you were able run yarn run-tunnelbroker-service yarn build-tunnelbroker-base yarn build-base-image successfully?

What are we removing from project.pbxproj?
Ah sorry, I actually expected the CI to fail and thought this diff would remain in a draft state so I didn't clean it up. But, I'll rebase once https://phabricator.ashoat.com/D3197 is landed and there should no longer be any change to project.pbxproj. I'll remove it from the diff.
Also you were able run yarn run-tunnelbroker-service yarn build-tunnelbroker-base yarn build-base-image successfully?
Haven't tried all of those yet. I just ran yarn build-all in the services directory. I'm kind of working under the assumption that if everything builds everything should continue to behave as before. Maybe that's not the case?

Now that everything is building, going to take a look at a few things before re-requesting review
- Removing unrelated changes to /project.pbxproj
- Seeing why we need to apt-get protobuf-compiler and it's not picking up protoc from path like it did on Alpine?
- See if we can avoid sudo

Did you perform any measurements when using ubuntu vs alpine? IIRC alpine was much faster when it came to installing packages for example.
I understand you want to change the distro, I'm just not sure whether ubuntu is the right choice.

Running yarn build-all from scratch in the services directory took about the same amount of time on my machine and the CI machine with Alpine and Ubuntu. Maybe the difference is more pronounced on x86 Macs?
IIRC alpine was much faster when it came to installing packages for example.
I wasn't able to reproduce this issue. My understanding was that the packages were only going to get installed once and cached afterward?
I understand you want to change the distro, I'm just not sure whether ubuntu is the right choice.
I think we agreed on Ubuntu during the Monday meeting. Is there an alternative distro you think we should go with? The primary reasons were:
- Issues with Alpine's use of musl which has partial ABI compatibility with the more widely used glibc. Specifically, this caused issues with the VSCode C++ language server which has experimental (read: broken) support for musl. This is the big one since it blocks a more sane dev environment
- Ubuntu is more widely used/team members have more familiarity with it/there's more documentation (official + stackoverflow type stuff) available online
- Perception that there's a stronger security team behind Ubuntu (I think @jimpo mentioned this and probably has more context)

That could be the case.
Anyway, we can defer rebuilding images and pushing them to the docker hub to someone who doesn't see a difference.
Basically, my first choice was ubuntu but I switched to alpine because it was recommended for docker images and significantly faster.

@atul This should run rm -rf /var/lib/apt/lists/* after the apt-get install. See https://docs.docker.com/develop/develop-images/dockerfile_best-practices/#apt-get. "In addition, when you clean up the apt cache by removing /var/lib/apt/lists it reduces the image size, since the apt cache is not stored in a layer."

@jimpo ah sorry I missed that last paragraph, I’ll put up a diff addressing that and link to it from here
