Manual synchronization of deployed applications

[ralf-berger]

@rawaa123 asked in #1140 (comment):

I would like to mention that whenever we try to push changes to Edge, they do not release automatically, and it takes considerable time for the changes to be reflected. Previously, when we pushed changes, it took only a few minutes for them to be released on Edge. Also, in Argo, I can see that it is OutOfSync. What could be causing this?

Zero downtime deployments are currently impossible due to the various stateful services that can't be scaled up. Updated builds of container images, including third-party ones like PostgreSQL, Redis, Neo4J etc., therefore cause unwanted service interruptions, possibly even dropped requests. This is why automatic updates to the environments are now restricted to a timespan outside working hours. During the day, ArgoCD detects changes to the configuration (e. g. updated container images) but doesn't apply those changes until late evening.

3- Is it possible to trigger synchronization by clicking on the 'SYNCHRONIZ' button as shown in the attachment? Or will this result in an error?

You can manually trigger the synchronization any time.
