Revision 394/395/396/397

September 11, 2024

Dear community,

Canonical’s newest Charmed PgBouncer operator has been published in the 1/stable channel.

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

• Revision 396 is built for amd64 on Ubuntu 22.04 LTS
• Revision 395 is built for amd64 on Ubuntu 20.04 LTS
• Revision 397 is built for arm64 on Ubuntu 22.04 LTS
• Revision 394 is built for arm64 on Ubuntu 20.04 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 pgbouncer --constraints arch=<arch> 

where <arch> can be amd64 or arm64.
