Building your own FRRouting Snap
========================================
(Tested on Ubuntu 16.04 with Snap Version 2, does not work on Ubuntu 15.x
which uses earlier versions of snaps)
1. Install snapcraft:
sudo apt-get install snapcraft
2. Checkout FRRouting under a **unpriviledged** user account
git clone https://github.com/frrouting/frr.git
cd frr
3. (Optional) Add extra version information to
`snapcraft/extra_version_info.txt`. Information in this file will
be displayed with the frr.version command (simple `cat` after
the display of the `zebra --version` output)
4. Run Bootstrap and make distribution tar.gz
./bootstrap.sh
./configure --with-pkg-extra-version=-MySnapVersion
make dist
Note: configure parameters are not important for the Snap building,
except the `with-pkg-extra-version` if you want to give the Snap
a specific name to mark your own unoffical build
This will build `frr-something.tar.gz` - the distribution tar and
the snapcraft/snapcraft.yaml with the matching version number
5. Create snap
cd snapcraft
snapcraft
You should now end up with `frr_something.snap`
Installing the snap
===================
(This can be done on a different system)
1. Install snapd
sudo apt-get install snapd
2. Install self-built frr snap. (`--force-dangerous` is required to
install a unsigned self-built snap)
snap install --force-dangerous ./frr*.snap
Connect the priviledged `network-control` plug to the snap:
snap connect frr:network-control core:network-control
See README.usage.md for more details on setting up and using the snap
DONE.
The Snap will be auto-started and running.
Operations
==========
### FRRouting Daemons
At this time, all FRRouting daemons are auto-started.
A daemon can be stopped/started with (ie ospf6d)
systemctl stop snap.frr.ospf6d.service
systemctl start snap.frr.ospf6d.service
or disabled/enabled with
systemctl disable snap.frr.ospf6d.service
systemctl enable snap.frr.ospf6d.service
### FRRouting Commands
All the commands are prefixed with frr.
frr.vtysh -> vtysh
frr.version -> Just gives version output (zebra --version)
frr.readme -> Returns simple README with hints on using FRR
frr.bgpd-debug -> Directly start each daemon (without service)
frr.isisd-debug
frr.ospf6d-debug
frr.ospfd-debug
frr.pimd-debug
frr.ripd-debug
frr.ripngd-debug
frr.ldp-debug
frr.zebra-debug
vtysh can be accessed as frr.vtysh (Make sure you have /snap/bin in your
path). If access as `vtysh` instead of `frr.vtysh` is needed, you can enable it
via a snap alias as follows:
sudo snap alias frr vtysh
This will add the vtysh command to your /snap/bin for direct access. The output of
sudo snap aliases
should list vtysh command alias as enabled:
App Alias Notes
frr.vtysh vtysh enabled
