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
.
This release of Charmed MySQL K8s requires Juju v.3.4.3
or 3.5.2+
. See the Technical details section for more information.
