Upgrade Alpine Linux without upgrading certain packages

mackowiakp · 11-03-2020, 09:27 AM

I have "NextCloud" installed in the docker. Docker (downloaded from GitHub) is based on Alpine Linux. As you know, Linux used in docker is not complete. I'd like to do automatic update/upgrade from cron. However, I would not like the upgrade to be performed on NextCloud packages, because I intend to use (for various reasons) a tool built into Nextcloud itself for this purpose.
However, the "apk" command doesn't have the "--exclude" option. So how can I upgrade the system without doing it on all "nextcloud*" packages?

AFAIU Alpine is a rolling release distro, which means that full upgrades are highly recommended, if not mandatory.
Be that as it may, I'm sure the Alpine Wiki can tell you how apk can be configured, and what other apk-tools exist besides the "apk" utility.

Alpine WIKI stands:

Quote:

The apk tool supports the following operations:
add Add new packages or upgrade packages to the running system
del Delete packages from the running system
fix Attempt to repair or upgrade an installed package
update Update the index of available packages
info Prints information about installed or available packages
search Search for packages or descriptions with wildcard patterns
upgrade Upgrade the currently installed packages
cache Maintenance operations for locally cached package repository
version Compare version differences between installed and available packages
index create a repository index from a list of packages
fetch download (but not install) packages
audit List changes to the file system from pristine package install state
verify Verify a package signature
dot Create a graphviz graph description for a given package
policy Display the repository that updates a given package, plus repositories that also offer the package
stats Display statistics, including number of packages installed and available, number of directories and files, etc.
manifest Display checksums for files contained in a given package

No "exclude" option or similar possibility. Lets take "apt". It is possible exclude packages from upgrade, but not in "apk".
So any replacement is possible? Any script or so...

SMH
This is how you get to know your tools:

check what executables belong to the various package management tools installed on your system.
while you're at it (list installed files of any given package) you can probably also see what sort of documentation is installed

Read those fruity man pages.
Hint: often configuration files also have their own man pages.
