v2.0.0

[yubiuser]

Breaking

• Move image location to ghcr.io/yubiuser/docker-event-monitor:latest

New features

• Add SMTP reporter
• Add SERVER_TAG feature

Improvements

• Use global variable for arguments to avoid passing pointers
• Simplifies waitgroup logic. Removes the need to pass the waitgroup pointer down in every function
• Handle the user-configurable delay conditionally
• Restructure title/message and add docker compose context and service names
• switch logging from logrus to zerolog

Fixes

• Fix mod.go version. Must be in format x.y, not x.y.z
• Enable APIVersionNegotiation for docker connection

CI:

• Use multiple runners to build images for different architectures (cuts down building a lot)
• Housekeeping: delete PR images after closing and all untagged-images that are not part of an multi-arch image
• Update Dependencies

I tested the SMTP feature and confirmed it working. I wondered if it is a good choice to force the mail_from wo also be the SMTP login name, I think this should be changed. Reasoning: I use several automated services that are capable of altering me via email (urlwatch, watchtower, ...). Currently, they all use the same SMTP account and simply send from different addresses so I can get this easily sorted into folders in my INBOX. For docker-event-monitor I had to create a new mailbox to achieve the same. Just a suggestion.

This is how, e.g., watchtower does it:

      WATCHTOWER_NOTIFICATIONS: email
      WATCHTOWER_NOTIFICATION_EMAIL_FROM: ...                      <----
      WATCHTOWER_NOTIFICATION_EMAIL_TO: ...
      WATCHTOWER_NOTIFICATION_EMAIL_DELAY: 2
      WATCHTOWER_NOTIFICATION_EMAIL_SERVER: ...
      WATCHTOWER_NOTIFICATION_EMAIL_SERVER_PORT: 587
      WATCHTOWER_NOTIFICATION_EMAIL_SERVER_USER: ...               <----
      WATCHTOWER_NOTIFICATION_EMAIL_SERVER_PASSWORD: ...
      WATCHTOWER_NOTIFICATION_EMAIL_SUBJECTTAG: my-server-name

This prompts an additional suggestion, issue #35 incoming :-)
