Automatic Updates

Starting from v1.19.0, new Komodo installs will automatically create the Global Auto Update Procedure, scheduled daily. If you don't have it, this is the Toml:

[[procedure]]
name = "Global Auto Update"
description = "Pulls and auto updates Stacks and Deployments using 'poll_for_updates' or 'auto_update'."
tags = ["system"]
config.schedule = "Every day at 03:00"

[[procedure.config.stage]]
name = "Stage 1"
enabled = true
executions = [
  { execution.type = "GlobalAutoUpdate", execution.params = {}, enabled = true }
]
info

You are also able to integrate GlobalAutoUpdate into other Procedures to coordinate the timing with other processes, such as backup. There is nothing special about this Procedure, it's just created by default for guidance / convenience.

How does it work?​

Both Stacks and Deployments allow you to configure Poll for Updates or Auto Update. When GlobalAutoUpdate is run, Komodo will loop through all the resources with either of these options enabled, and run PullStack / PullDeployment in order to pick up any newer images at the same tag. Note that in order to work, it requires use of a "Rolling" image tag, such as :latest.

info

If you use git sources Stacks and want to automatically update image tags, check out Renovate

For resources with Poll for Updates enabled and an Alerter configured, it will send an alert that a newer image is available, and display the update available indicator in the UI

For resource with Auto Update enabled, it will go ahead and Redeploy just the services with newer images (by default). If an Alerter is configured, it will also send an alert that this occured.
