Revision 267/268/269 (dpe/candidate only)

Dear community,

Canonical’s newest Charmed MySQL Router operator has been published in the dpe/candidate channel.

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

  • Revision 267 is built for amd64 on Ubuntu 22.04 LTS
  • Revision 268 is built for amd64 on Ubuntu 20.04 LTS
  • Revision 269 is built for arm64 on Ubuntu 22.04 LTS

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

Otherwise, it can be done at deploy time with the --constraints flag:

juju deploy mysql-router --constraints arch=<arch>

where <arch> can be amd64 or arm64.
