scylladb/scylla container image doesn't include systemctl binary, while it is used by perftune.py script shipped within the same image. Scylla Operator runs this script to tune Scylla nodes/containers, expecting its all dependencies to be available in the container's PATH. Without systemctl, the script fails on systems that run irqbalance (e.g., on EKS nodes) as the script tries to reconfigure irqbalance and restart it via systemctl afterwards. Fixes: scylladb/scylla-operator#3080 Closes scylladb/scylladb#28567
Docker image with a self-built executable
The following instructions will allow you to build a Docker image which contains a combination of some tools from the nightly build in http://downloads.scylladb.com/ (as described above) but with a Scylla executable which you build yourself.
Do the following in the top-level Scylla source directory:
-
Build your own Scylla in whatever build mode you prefer, e.g., dev.
-
Run
ninja dist-dev(with the same mode name as above) to prepare the distribution artifacts. -
Run
./dist/docker/redhat/build_docker.sh --mode devThis creates a docker image as a file, in the OCI format, and prints its name, looking something like:
oci-archive:build/dev/dist/docker/scylla-4.6.dev-0.20210829.4009d8b06 -
This file can copied to a docker repository, or run directly with podman:
podman run oci-archive:build/dev/dist/docker/scylla-4.6.dev-0.20210829.4009d8b06Often with additional parameters, as in docs/alternator/getting-started.md:
podman run --name scylla -d -p 8000:8000 oci-archive:... --alternator-port=8000 --alternator-write-isolation=always
