Wroking with cgroups

cgroups.sh

# Taken from here: https://wiki.archlinux.org/index.php/cgroups

# You need: libcgroup and cgmanager apps.
# Then start the daemon:
sudo systemctl start cgmanager.service


# Creating the group
sudo cgcreate -a arsham:users -t arsham:users -g memory,cpu:GROUP_NAME

# To create subgroups
sudo cgcreate -a arsham:users -t arsham:users -g memory,cpu:GROUP_NAME/SUB_GROUP_NAME

# Limiting memory
echo 100000000 > /sys/fs/cgroup/memory/GROUP_NAME/memory.limit_in_bytes

# Limiting CPU shares
echo 1 > /sys/fs/cgroup/cpu/GROUP_NAME/cpu.shares

# Running an app in the group
cgexec -g cpu,memory:GROUP_NAME APP_NAME

# Deleting the group
sudo cgdelete -g memory,cpu:GROUP_NAME

# If you already have a subgroup be sure to remove the subgroup first
sudo cgdelete -g memory,cpu:GROUP_NAME/SUB_GROUP_NAME
