Revision 180/181

_{September 2, 2024}

Dear community,

Canonical’s newest Charmed MySQL K8s operator has been published in the 8.0/stable channel.

Due to the newly added support for arm64 architecture, the MySQL K8s charm now releases two revisions simultaneously:

• Revision 180 is built for amd64 ( mysql-image r113 )
• Revision 181 is built for arm64 ( mysql-image r113 )

To make sure you deploy for the right architecture, we recommend setting an architecture constraint for your entire Juju model.

Otherwise, you can specify the architecture at deploy time with the --constraints flag as follows:

juju deploy mysql-k8s --constraints arch=<arch> --trust

where <arch> can be amd64 or arm64.
