Revision 381/382

September 11, 2024

Dear community,

Canonical’s newest Charmed PostgreSQL K8s operator has been published in the 14/stable channel.

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

  • Revision 381 is built for amd64 on Ubuntu 22.04 LTS (postgresql-image r162)
  • Revision 382 is built for arm64 on Ubuntu 22.04 LTS (postgresql-image r162)

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 postgresql-k8s --trust --constraints arch=<arch> 

where <arch> can be amd64 or arm64.
