NetOTA provides a pair of utilities for working with SysOTA repositories.
The repository is stored in $SNAP_COMMON/repository, or
/var/snap/netota/common/repository. Upon installation, a sample repository
with a single package and several streams is copied there for to illustrate
the data structures. The repository should be removed and replaced with a git
checkout. Updates to the repository should be performed by pulling changes.
This allows working with changes more easily, including reverting faulty
updates.
The systemd service snap.netota.netotad.service can be restarted to verify
changes to the repository and serve new content. Alternatively, the SIGHUP
signal may be sent to the service to achieve in-place replacement without
downtime. If the new repository is malformed, old repository is served and
an error is logged to the system journal.
The address at which NetOTA listens on is managed by the snap configuration
system. By default that is localhost and port 8000.
To use NetOTA without a reverse proxy you must set the IP to listen to to the desired IP (or 0.0.0.0 to listen on all the interfaces). This can be done with
snap set netota address=...
Please make sure to include the port to listen on as well.
Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap is available for CentOS 7.6+, and Red Hat Enterprise Linux 7.6+, from the Extra Packages for Enterprise Linux (EPEL) repository. The EPEL repository can be added to your system with the following command:
sudo yum install epel-release
Snap can now be installed as follows:
sudo yum install snapd
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install netota, simply use the following command:
sudo snap install netota
Browse and find snaps from the convenience of your desktop using the snap store snap.
