Hi, Could Ursa Labs buy the Travis CI's "5 Concurrent plan" ($249/month) only for this month? It's just for the 3.0.0 release. We can stop the plan after we release 3.0.0.
See also: https://docs.travis-ci.com/user/billing-overview/#concurrency-based-plans Background: We have only two Crossbow task types that depend on Travis CI: building .deb/.rpm for ARM64 and testing Homebrew on macOS We'll be able to migrate testing Homebrew on macOS tasks to other CI like GitHub Actions easily. But building .deb/.rpm for ARM64 tasks are difficult. Here are failed candidates: 1. Using GitHub Actions with x86_64 host + QEMU + ccache We know that building .deb/.rpm for ARM64 with x86_64 host + QEMU takes 6h+. Hypothesis: If we use ccache and share cache with builds, we may be able to reduce build time. Fact: We can't share cache between Crossbow tasks. Because Crossbow creates a new branch for each task and doesn't use the default branch. The GitHub Actions cache feature doesn't share cache between branches: https://docs.github.com/en/free-pro-team@latest/actions/guides/caching-dependencies-to-speed-up-workflows#matching-a-cache-key 2. Using Drone Cloud like our conda-*-aarch64 tasks Building .deb/.rpm tasks prepare build in base host and run a Docker container to build .deb/.rpm. We need to run a Docker container in CI. Travis CI and GitHub Actions can do it. It seems that Drone Cloud uses Docker pipeline: https://docs.drone.io/yaml/docker/ We need Docker-in-Docker support for building .deb/.rpm tasks. But Drone Cloud doesn't support Docker-in-Docker: https://discourse.drone.io/t/run-docker-container-in-docker/5704/2 We may be able to use Bulidkite based CI for 4.0.0.
