@stasadev I added your DDEV gmail address to the upsun org "DDEV", hopefully that gives you access. If not we'll work with them to sort it out.

• You'll need to add your ssh pubkey into your Upsun account
• The test target (and manual testing environment) is https://console.upsun.com/ddev/nqorjgl7ohua4
• I created the "main" environment (which we don't really use) and a pull and push environment, which will be used for the test
• The login to the drupal site is the same on all and is in 1Password. I would have left it admin/admin but this is publicly exposed, so might as well have a real password even though it's annoying.
• Add upsun tool into the web image and push a new image version
• We'll need an API token configured, added to github actions, and put in 1Password
• Copy platform.yaml to upsun.yaml to make it work, improve either or both along the way.
• After manual testing, create the tests; will be the same as the TestPlatformPull and TestPlatformPush
• There are no worries about the actual content of any of these environments, we can recreate as needed. And you can push to git, etc.

I saw the tip about this and said out loud, "What's upsun?" Kind of like "What's up, son?" Reminded me of one of those jokes like "What's a motto?" "Nothing. What's a motto with you?"
