Updates for an EGroupware installation take place in different ways:
Package updates via apt/yum directly via gateway or with configured proxy.
- (Docker)Container updates directly via gateway or with configured proxy.
An EGroupware system with direct internet access (usually via gateway) can thus update itself automatically in a standard installation (the Conatainer).
If a system does not have direct internet access (via gateway), the necessary access to updates can be created by configuring a proxy, if necessary.
While for apt/yum the configuration is set at the appropriate place, for Docker a proxy must be configured separately.
On a Debian 10, for example
This as an example. Depending on the OS and Docker version, this may work differently now and in the future.
