Add resource-limit and resource-usage containers to YANG model. Podman, and later conmon, enforce CPU and memory limits in a delegated cgroupsv2 hierarchy managed by Finit. Resource usage is queried from 'podman inspect', which has more nodes than what is currently possible to limit. Requires Finit 4.15, or later. Signed-off-by: Joachim Wiberg <troglobit@gmail.com>
Introduction
Statd is designed to be integrated into Infix and supply the operational
database with data. To do this it uses companion binaries written in
python, these are located in the python directory.
Run outside Infix
Prerequisites
There are some requirements set on your computer to run statd locally.
- An Ubuntu based system
- lldpd
- python3
- libite
- libsrx
- python-poetry
- sysrepo (At least the same version as Infix)
- libyang (At least the same version as Infix)
Install YANG modules in local sysrepo
This requires that you first build Infix, since netopeer2 and sysrepo are responsible for installing their own YANG files.
user@host ~/infix$ export TARGET_DIR="output/target/"
user@host ~/infix$ export NETOPEER2_SEARCHPATH=$TARGET_DIR/usr/share/yang/modules/netopeer2/
user@host ~/infix$ export SYSREPO_SEARCHPATH=$TARGET_DIR/usr/share/yang/modules/sysrepo/
user@host ~/infix$ export LIBNETCONF2_SEARCHPATH=$TARGET_DIR/usr/share/yang/modules/libnetconf2/
user@host ~/infix$ export CONFD_SEARCHPATH=$TARGET_DIR/usr/share/yang/modules/confd/
user@host ~/infix$ export TEST_MODE_SEARCHPATH=$TARGET_DIR/usr/share/yang/modules/test-mode/
user@host ~/infix$ export ROUSETTE_SEARCHPATH=$TARGET_DIR/usr/share/yang/modules/rousette/
user@host ~/infix$ export SEARCH_PATH="$NETOPEER2_SEARCHPATH $SYSREPO_SEARCHPATH $LIBNETCONF2_SEARCHPATH $CONFD_SEARCHPATH $TEST_MODE_SEARCHPATH $ROUSETTE_SEARCHPATH"
user@host ~/infix$ ./utils/srload src/confd/yang/sysrepo.inc
user@host ~/infix$ ./utils/srload src/confd/yang/libnetconf2.inc
user@host ~/infix$ ./utils/srload src/confd/yang/netopeer2.inc
user@host ~/infix$ ./utils/srload src/confd/yang/confd.inc
user@host ~/infix$ ./utils/srload src/confd/yang/rousette.inc
user@host ~/infix$ ./utils/srload src/confd/yang/test-mode.inc
Build and install python companion binaries
user@host ~/infix/src/statd/python$ ./local_install.sh
This will install the binaries in ~/.local/bin
Build and install statd
user@host ~/infix/src/statd$ ./configure --with-yanger-dir=$HOME/.local/bin
user@host ~/infix/src/statd$ make
user@host ~/infix/src/statd$ sudo make install
Running statd
Since the yanger binary, for example, reads the shadow database, you
can expect different results if running statd as root or not.
user@host ~/infix/src/statd$ statd
