What happened?

After updating docker engine i got error:

unable to connect to docker: API error (400): client version 1.18 is too old. Minimum supported API version is 1.24, please upgrade your client to a newer version

How to reproduce it?

Background

In docker version 25.0 they have changed the minimum supported api version from 1.12 to 1.24.
Weave only supports docker has are dependent on docker api 1.18.

Fix for Docker version 25.0

Create file: /etc/systemd/system/docker.service.d/min-api-version.conf

[Service]
Environment="DOCKER_MIN_API_VERSION=1.18"

systemctl daemon-reload

IMPORTANT

Support for API versions lower than 1.24 will be permanently removed in Docker Engine v26, and the minimum supported API version will be incrementally raised in releases following that.

restart of docker isn't necessary. It will sort it out itself but will take longer for it to handle it.

Maybe, but i spent some time figuring out why it's not working. And this reccomendation is from docker docs: https://docs.docker.com/config/daemon/systemd/ (4th point)

Some great work from @rajch This will resolve weave for docker v26.0
