I checked comparing "--no-recommends", "--recommends" and default using e.g.:

podman run --rm -it registry.opensuse.org/opensuse/tumbleweed zypper -n in --dry-run --recommends autoconf automake gcc-c++ libtool pkgconfig\(opencv\) pkg-config perl\(Module::CPANfile\) pkgconfig\(fftw3\) pkgconfig\(libpng\) pkgconfig\(sndfile\) pkgconfig\(theoraenc\) make rubygem\(sass\) python3-base python3-requests python3-future git-core rsync curl postgresql-devel postgresql-server qemu qemu-kvm qemu-tools tar xorg-x11-fonts sudo chromedriver

and found no difference between default and "--no-recommends", what would install 1.6 GiB. With "--recommends" I would get 2.2 GiB so that won't help.

I have not observed this lately. We can bring it back to our backlog when we see it again more than once.

context deadline exceeded

I don't find good information how to handled "context deadline exceeded". I only know of https://support.circleci.com/hc/en-us/articles/360045268074-Build-Fails-with-Too-long-with-no-output-exceeded-10m0s-context-deadline-exceeded- regarding the "no output timeout".

I have found nothing regarding retrying when within the "Spin Up Environment" step.

I see it as problematic that we download a 500MB+ image in every job and have not much control over it. Maybe we can either optimize the image, move some package installations to a later step or not even use the image until in a later step?

We will try with just a different time https://github.com/os-autoinst/openQA/pull/3451

If the different time slot works good enough we might be ok with just this change then.

So after many nights where the nightly pipeline failed the one from yesterday just passed fine at the new time: https://app.circleci.com/pipelines/github/os-autoinst/openQA/4447/workflows/78a764f1-2b6b-4b91-b920-3e11bc57c1cc

I consider it suboptimal that the repeated image downloading of 500MiB takes 3-5 minutes but it seems we might have found a good approach for the problem at hand. Thanks tinita for the good idea of just running the pipeline at a different time of day.

https://app.circleci.com/pipelines/github/os-autoinst/openQA/4465/workflows/fc241df3-9822-4a09-90b0-a03ac4589dff

so much for that :D same output as in #67855#note-7

I researched again if I could find anything regarding setting timeouts on circleCI but again the only real think I found is "no_output_timeout" for "run" commands but not for the "Set up environment" part.

I am currently out of ideas except for ditching circleci :(

this now hits PRs of users reproducibly as well where even retry does not help, see https://github.com/os-autoinst/openQA/pull/3519#issuecomment-724252129

https://discuss.circleci.com/t/speed-up-spin-up-environment-with-custom-easticsearch-docker-image/34393/2 explains that we can try to have either more layers preserved in the container image or do more run-time installations and less up-front.

https://github.community/t/speed-comparison-github-actions-takes-3m-32s-circle-ci-takes-12s/17780 shows that circleCI can be quite fast, e.g. compared to github actions but this only works if using container images that can use the circleCI base images which are for example described in https://discuss.circleci.com/t/new-ubuntu-base-convenience-image-public-beta/33129 which are Ubuntu based. Does not help us much.

I am not sure if I have ever seen an image being already present on a host so we need to redownload every time. This is also what others report: https://discuss.circleci.com/t/spin-up-environment-docker-cache/11146/12

The combination of a heavy image in combination with downloading from slow registry.opensuse.org to circleCI workers have a significant impact here.

I am trying different approaches now:

• https://github.com/os-autoinst/openQA/pull/3527 specifying "NoSquash" option for the base image

This looks promising so far. Instead of

• https://github.com/os-autoinst/openQA/pull/3528 using an image that just install openQA-devel in one step -> image is 550MB so even 10MB bigger than default

• https://github.com/os-autoinst/openQA/pull/3529 completely remove the base image, use a much smaller leap vanilla image and go with manually installing packages

The cache job looks fine in https://app.circleci.com/pipelines/github/os-autoinst/openQA/4807/workflows/6c702455-a0fc-4196-a51a-dc3d50aa977f/jobs/45731 but "t" fails in https://app.circleci.com/pipelines/github/os-autoinst/openQA/4807/workflows/6c702455-a0fc-4196-a51a-dc3d50aa977f/jobs/45735 due to missing tar in the base image.

Created https://build.opensuse.org/package/view_file/home:okurz:branches:devel:openQA:pr3529_use_tiny_base/base/Dockerfile?expand=1 which uses leap but only installs tar.

EDIT: … and gzip. and then postgresql-server in ci-packages.txt . Now https://app.circleci.com/pipelines/github/os-autoinst/openQA/4824/workflows/15630d74-7d73-46b4-8ef2-f05e4f7665cc/jobs/45912 fails as postgresql refuses to run as root, https://app.circleci.com/pipelines/github/os-autoinst/openQA/4824/workflows/15630d74-7d73-46b4-8ef2-f05e4f7665cc/jobs/45913 fails to find the "shellcheck" command even though. I guess I can go back and keep the user.

Created https://github.com/os-autoinst/openQA/pull/3536 to just strip down the package installation within the base package without changing the other instructions in the container. Called osc branch home:okurz:branches:devel:openQA:pr3528_use_devel_package_in_base_image base home:okurz:branches:devel:openQA:pr3536_circleci_cache_base_image_less_packages, adjusted https://build.opensuse.org/package/view_file/home:okurz:branches:devel:openQA:pr3536_circleci_cache_base_image_less_packages/base/_service?expand=1 to point to the correct branch https://github.com/okurz/openQA/tree/fix/circleci_cache_base_image_less_packages, set https://build.opensuse.org/projects/home:okurz:branches:devel:openQA:pr3536_circleci_cache_base_image_less_packages/meta to publish enable, looked up the published container on https://registry.opensuse.org/cgi-bin/cooverview?srch_term=project%3D%5Ehome%3Aokurz , created https://github.com/os-autoinst/openQA/pull/3537 with a temporary test using the temporary image

https://github.com/os-autoinst/openQA/pull/3530 merged.

https://github.com/os-autoinst/openQA/pull/3536 is still waiting for an image to be published on registry.o.o , seems like that is slow to publish today. https://build.opensuse.org/package/show/devel:openQA:ci/base shows currently "failed" and a build log from 2020-11-09. Something is fishy but waiting solves many problems :)

had support by andriinikitin and I am continuing with this. Feedback cycles are a bit long because I am relying on circleCI in the loop so can't just test it locally. Well, could use https://circleci.com/docs/2.0/local-cli/ :)

https://github.com/os-autoinst/openQA/pull/3536 looks ok now, waiting for review.

PR merged. https://build.opensuse.org/package/view_file/devel:openQA:ci/base/_service:download_url:Dockerfile?expand=1 was automatically updated.

I will wait until this is built and at least one CI job passed.

andrii-suse provided a helpful comment in https://github.com/os-autoinst/openQA/pull/3572#issuecomment-731512892
what we could try in the second try to bring in the approach of the stripped down CI image:

@okurz Ugh I see what went wrong with #3536 .
It built new cache on top of old ci:base image, so many packages were not included into cache, because they were not downloaded, because they were already installed.
Then ci:base was rebuilt according to Dockerfile changes, and next PR did pull updated ci:base image and tried to install the cache packages on top of it, which obviously failed.
I guess we can just introduce ci:base_v1 or ci:minimal for such purposes, instead of dealing with chicken/egg problem. :\ Then retry #3536

But for now I would like to monitor if the circleCI jobs actually still fail with the same rate as in before. The last Nbg datacenter power outage has caused quite some "changes" so maybe even download from registry.opensuse.org behaves different now :D

I have not seen timeouts in past days after the nbg power outage 2020-11-18. Maybe the fresh boot of so many systems helped to resolve some issues :D

I will reduce prio now and we can check back later if we want to warm up the same approach again.

not planning to continue unless we see the errors again.
