# 下载 kubeedge
$ wget https://github.com/kubeedge/kubeedge/releases/download/v1.7.1/kubeedge-v1.7.1-linux-arm.tar.gz

# 解压
$ tar zxvf kubeedge-v1.7.1-linux-arm.tar.gz

$ mv kubeedge-v1.7.1-linux-arm/edge/edgecore /usr/local/bin

$ mkdir -p /etc/kubeedge/config

$ edgecore --defaultconfig > /etc/kubeedge/config/edgecore.yaml

# With --defaultconfig flag, users can easily get a default full config file as reference, with all fields (and field descriptions) included and default values set. 
# Users can modify/create their own configs accordingly as reference. 
# Because it is a full configuration, it is more suitable for advanced users.

主要 修改容器运行时、cgroup 驱动

运行

edgecore

如下错误：

edgecore[45472]: E0407 06:52:35.569727 45472 edged.go:742] Failed to start container manager, err: system validation failed - Following Cgroup subsystem not mounted: [memory] edgecore[45472]: E0407 06:52:35.569777 45472 edged.go:293] initialize module error: system validation failed - Following Cgroup subsystem not mounted: [memory]

# 内存资源的cgroups机制没有开启

# 修改启动参数
$ vim /boot/cmdline.txt

# 追加
cgroup_memory=1 cgroup_enable=memory


# 查看可用的cgroup
$ cat /proc/cgroups
