Simplify your snapcraft.yaml development with Jsonnet
Use Jsonnet syntax to build your snapcraft.yaml. Jsonnet allows you to import and use third-party snippet libraries to save writing the same boilerplate over and over again. The author of this snap has documented and catalogued several libraries, which can be found via https://sc-jsonnet.readthedocs.io/en/latest/available-libraries.html.
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.
Enable snapd
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.
Install sc-jsonnet
To install sc-jsonnet, simply use the following command:
