summary: High availability VRRP and load-balancing for Linux
description: |
  Keepalived provides simple and robust loadbalancing and high-availability
  to Linux based infrastructures using VRRP and the well-known Linux Virtual
  Server (IPVS) kernel module.

grade: stable
confinement: classic

# linux-libc-dev for 5.0, 4.18 and 3.10 are no longer available via
#    http://security.ubuntu.com/ubuntu/pool/main/l/linux/
# or
#    http://ports.ubuntu.com/pool/main/l/linux/
# and will disappear for other versions is due course.
#
# To find the relevant files, go to launchpad.net/ubuntu/CODENAME/ARCH/linux-libc-dev
#   where CODENAME is, for example cosmic for Ubuntu 18.10, and ARCH is each of amd64,
#   i386, ppc64el, arm64, armhf and s390x.
# Select the most recent version, and click on link under Version column (RHS). Under
#   Downloadable files is a link to the .deb file. That is what we need in DEB_URL.
#
# We should probably update the locations of the files to use this more difficult way
#   of finding them once the Ubuntu version that provides them goes EOL.
