 # 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
 
-Edit apk's repositories config:
+Run `setup-apkrepos` command, then you'll get a menu list like this:
 
-```sh
-vi /etc/apk/repositories

-## Enable CGroup2
+Then input `c` to enable community repo.
 
-Edit OpenRC's config file:
-
-```sh
-vi /etc/rc.conf

-Then edit `rc_cgroup_mode`, defaultly it would be `#rc_cgroup_mode="hybrid"`, we should switch to `unified` to make sure CGroup2 in default.

+# 在 Alpine Linux 上运行
+
+**注意：** 
+1. Alpine Linux 3.18 或更新版本已完全支持开箱即用的 eBPF，旧版本的 Alpine Linux 需要自己构建内核。
+2. 从 3.20 版开始，由于 Alpine Linux 的跨 CPU 架构兼容性问题，官方禁用了 dae 所需的一些功能，因此默认情况下只能使用 `linux-virt` 运行 dae。对于 `linux-lts` 或 `linux-edge`，你应该自己构建内核。
+3. 本教程适用于 Alpine Linux 3.20 及更新版本。
+
+## 启用 Community Repo
+
+运行 `setup-apkrepos` 命令，然后你会看到这样的菜单列表：
+
+```
+ (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
+```
+
+然后输入 ``c` 启用社区仓库。
+
+## 启用 CGgroups
+
+启用 `cgroups` 服务：
+
+```sh
+rc-update add cgroups boot
+```
+
+## 挂载 bpf
+
+编辑 `/etc/init.d/sysfs`：
+
+```sh
+vi /etc/init.d/sysfs
+```
+
+在 `mount_misc` 部分添加以下内容：
+
+```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
+```
+
+请注意，脚本 `/etc/init.d/sysfs` 的格式必须正确，否则 `/etc/init.d/sysfs` 将被删除。
+
+## 安装 dae
+
+安装程序： <https://github.com/daeuniverse/dae-installer/>
+
+此安装程序提供了一个 dae 的 OpenRC 服务脚本，安装后，您需要在 `/usr/local/etc/dae/config.dae` 中添加一个配置文件，然后将其权限设置为 600 或 640：
+
+```sh
+chmod 640 /usr/local/etc/dae/config.dae
+```
+
+如果配置文件已准备就绪，那就可以启动 dae 服务了：
+
+```sh
+rc-service dae start
+```
+
+## 随系统启动
+
+使用 `rc-update` 启用 dae 服务：
+
+```sh
+rc-update add dae
+```
