# Run on Alpine Linux
|
|
|
|
**Note:**
|
|
1. Alpine Linux 3.18 or newer verison has full eBPF support out-of-box, older version of Alpine Linux need to build kernel by yourself.
|
|
2. From version 3.20, Alpine Linux has officially disabled some features dae needed beacuse of Alpine Linux's cross CPU architectures compatibility, so only `linux-virt` can be used to run dae defaultly. For `linux-lts` or `linux-edge`, you should build the kernel by yourself.
|
|
3. This tutorial is for Alpine Linux 3.20 and newer.
|
|
|
|
## Enable Community Repo
|
|
|
|
Run `setup-apkrepos` command, then you'll get a menu list like this:
|
|
|
|
```
|
|
(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
|
|
```
|
|
|
|
Then input `c` to enable community repo.
|
|
|
|
## Enable CGroups
|
|
|
|
Enable `cgroups` service:
|
|
|
|
```sh
|
|
rc-update add cgroups boot
|
|
```
|
|
|
|
## Mount bpf
|
|
|
|
Edit `/etc/init.d/sysfs`:
|
|
|
|
```sh
|
|
vi /etc/init.d/sysfs
|
|
```
|
|
|
|
Add the following to the `mount_misc` section:
|
|
|
|
```sh
|
|
# 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
|
|
```
|
|
|
|
Be careful that the format of the script `/etc/init.d/sysfs` must be correct, or `sysfs` service will be failed.
|
|
|
|
## Install dae
|
|
|
|
Installer: <https://github.com/daeuniverse/dae-installer/>
|
|
|
|
This installer offered an OpenRC service script of dae, after installation, you should add a config file to `/usr/local/etc/dae/config.dae`, then set its permission to 600 or 640:
|
|
|
|
```sh
|
|
chmod 640 /usr/local/etc/dae/config.dae
|
|
```
|
|
|
|
If your config file is ready to work, then you can start dae service:
|
|
|
|
```sh
|
|
rc-service dae start
|
|
```
|
|
|
|
## Start dae at boot
|
|
|
|
Use `rc-update` to enable dae service:
|
|
|
|
```sh
|
|
rc-update add dae
|
|
```
