Revision 274/275

TODO

This page is a work in progress for a future release.

Dear community,

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

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

  • Revision 275 is built for amd64
  • Revision 274 is built for arm64

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 --constraints arch=<arch>

where <arch> can be amd64 or arm64.

This release of Charmed MySQL requires Juju v.3.4.3 or 3.5.2+. See the Technical details section for more information.
