Include:Using Internet Repositories for apk-tools

Edit the /etc/apk/repositories file using an editor (nano for instance) and if necessary, add references to the Alpine package repositories. In the example below, the file references the Alpine CD, so that if a requested package is available on the local media, it will be obtained from there instead of being downloaded from the remote repository:

Contents of /etc/apk/repositories

/media/cdrom/apks http://dl-3.alpinelinux.org/alpine/v3.3/main

To upgrade, for example, from version 3.3 to 3.4,simply change:

http://dl-3.alpinelinux.org/alpine/v3.3/main

to

http://dl-3.alpinelinux.org/alpine/v3.4/main

So that the file will look like this:

Contents of /etc/apk/repositories

/media/cdrom/apks http://dl-3.alpinelinux.org/alpine/v3.4/main

Note: Starting with version 3.3, there is a new repository called community. Many packages have been moved from the main repository to the community repository to indicate that they are not guaranteed to be supported beyond six months. If you are using any of these packages, be sure to add the community repository. For example: http://dl-3.alpinelinux.org/alpine/v3.3/community

Above, only one possible repository is shown, however, http://dl-3.alpinelinux.org/alpine/ may also be replaced with any of the mirrors from: http://rsync.alpinelinux.org/alpine/MIRRORS.txt

After updating the repositories file, the latest index of available packages can be obtained with:

apk update

Tip: Adding the -U/--update-cache to another apk command, as in apk add -U ... or apk upgrade -U, has the same effect as running apk update before the other apk command.
