Update to kamal-proxy 0.8.0

[djmb]

Proxy changes:

• Add option to use custom TLS certificates (Enable docker secrets as a more secure alternative to build args #17)
• Don't buffer SSE responses (Server monitoring #36)
• Allow routing to wildcard subdomains (Set .env files to 0600 so they're not world-readable #45)

Custom TLS certificates not supported in Kamal itself yet. Buffering SSE responses and wildcard subdomains will work without any Kamal changes.

I didn't want to create a new issue, so commenting in here. Am I correct that currently there is no way to specify the kamal-proxy version without a code change in Kamal itself?

@karls I was about to ask the same question, you beat me to it :D. FWIW: I was looking in the CLI commands for a kamal proxy upgrade.

@karls That's correct, it's currently hardcoded in the code.

kamal/lib/kamal/configuration.rb

Line 17 in e34031f

PROXY_MINIMUM_VERSION = "v0.7.0"

I discovered that you can upgrade the Kamal Proxy using the following command:

kamal proxy reboot

If it's running old version, and new version is available, then it will upgrade, e.g:

ERROR (RuntimeError): Exception while executing on host certsdiscount-app1: kamal-proxy version v0.6.0 is too old, please reboot to update to at least v0.7.0

thanks @tuladhar. I tried rebooting. however, it did not work.

Same here. I tried rebooting again, but it didn’t update beyond what’s hardcoded in the code.

Yes right now the version is fixed entirely. But I think we'll allow updating to later versions, or running your own image if you want to fork kamal-proxy
