Run on Alpine Linux

This tutorial covers Alpine Linux 3.20 and later.

• Alpine Linux 3.18 and later have full eBPF support out of the box. Earlier versions require a custom kernel build.
• Starting with Alpine Linux 3.20, some features required by dae are disabled for cross-architecture compatibility. Only linux-virt runs dae by default; linux-lts and linux-edge require a custom kernel build.

Enable Community Repo

Run setup-apkrepos to open this menu:

sudo

sudo setup-apkrepos

root

setup-apkrepos

 (f)    Find and use fastest mirror
 (s)    Show mirrorlist
 (r)    Use random mirror
 (e)    Edit /etc/apk/repositories with text editor
 (c)    Community repo enable
 (skip) Skip setting up apk repositories

Enter c to enable the community repository.

Enable CGroups

Enable the cgroups service:

sudo

sudo rc-update add cgroups boot

root

rc-update add cgroups boot

Mount BPF

Edit /etc/init.d/sysfs:

sudo

sudo vi /etc/init.d/sysfs

root

vi /etc/init.d/sysfs

Add the following to the mount_misc section:

        # Setup Kernel Support for bpf file system
        if [ -d /sys/fs/bpf ] && ! mountinfo -q /sys/fs/bpf; then
                if grep -qs bpf /proc/filesystems; then
                ebegin "Mounting eBPF filesystem"
                mount -n -t bpf -o ${sysfs_opts} bpffs /sys/fs/bpf
                eend $?
                fi
        fi

Check the syntax in /etc/init.d/sysfs. Errors will cause the sysfs service to fail.

sudo

sudo reboot

root

reboot

Install dae

Use dae-installer, which provides an OpenRC service script. After installation, create /usr/local/etc/dae/config.dae and set its permissions to 600 or 640:

sudo

sudo chmod 640 /usr/local/etc/dae/config.dae

root

chmod 640 /usr/local/etc/dae/config.dae

Once the configuration is ready, start dae:

See Start now.

Start dae at Boot

Use rc-update to enable the dae service:

See Enable at boot.
