Failed to listen: bind: Cannot assign requested address: 99 (Cannot assign requested address)

I see this error, when the second is trying to join the cluster.

In the Dockerfile

RUN apt-get update && apt-get install -y --no-install-recommends \
        galera-4 \
        galera-arbitrator-4 \
        mysql-wsrep-8.0 \

Any help would be appreciated, thanks.

You don’t need these unless you are running the actual arbitrator daemon.

Looks like MySQL is trying to bind to a non-existent IP address inside the docker container. Change your config to use to bind to all IPs inside the container.

Thanks @matthewb for your response, but I already have in my.cnf file.
I see some other people also have the similar issue.

Its working fine, if the docker container is mapped to “host” network.
So, is the docker “host” network mandatory for SST/IST to work with Galera4-MySQL8?

I’ve not read that is a hard requirement. Maybe try adding --privileged or other CAP_ADD network permissions if you need it to work in bridged mode.

I would also recommend switching to Percona XtraDB Cluster 8, which uses an enhanced Galera4 + Percona MySQL 8.0. And if you’re looking at Kubernetes, our Operator is 2nd to none in terms of functionality and stability.
