## 安装 Charm 2.x

如果是使用 1.24 版本以及以后, 此步骤可以跳过

```Bash
snap install charm --channel=2.x --classic
```

## 获取特定版本的 Bundle

```Bash
wget https://raw.githubusercontent.com/charmed-kubernetes/bundle/main/releases/1.21/bundle.yaml
```

或是

```Bash
# 对于 1.23 版本以及以前
charm pull cs:~containers/charmed-kubernetes-657

# 对于 1.24 版本以及以后
juju download ch:charmed-kubernetes --channel 1.24/stable --series focal
```

## 拉取 Bundle 中的相关组件

```Bash
# 对于 1.23 版本以及以前
charm pull cs:~containers/etcd-607

# 对于 1.24 版本以及以后
juju download ch:etcd --channel 1.24/stable --series focal
```

## 拉取相关组件的资源包

```Bash
# 对于 1.23 版本以及以前
charm list-resources cs:~containers/calico-812
wget https://api.jujucharms.com/charmstore/v5/~containers/calico-812/resource/calico/1027 -O calico.tgz
wget https://api.jujucharms.com/charmstore/v5/~containers/calico-812/resource/calico-arm64/1026 -O calico-arm64.tgz
wget https://api.jujucharms.com/charmstore/v5/~containers/calico-812/resource/calico-node-image/709 -O calico-node-image.tgz
wget https://api.jujucharms.com/charmstore/v5/~containers/calico-812/resource/calico-upgrade/854 -O calico-upgrade.tgz
wget https://api.jujucharms.com/charmstore/v5/~containers/calico-812/resource/calico-upgrade-arm64/854 -O calico-upgrade-arm64.tgz

# 对于 1.24 版本以及以后
unzip xxx.charm
build-xxx-resource.sh
# 或
前往 https://charmhub.io/calico/resources/calico?channel=1.24/stable 下载对应的 Revision  
```

## 向 Controller 上传资源

```Bash
# ex: juju attach-resource <charm-name> resource-name=<filepath>
juju attach-resource calico calico=/home/sa/charm/calico/calico-amd64.tar.gz
juju attach-resource calico calico-upgrade=/home/sa/charm/calico/calico-upgrade-amd64.tar.gz
```

## 回收节点

```Bash
/sbin/remove-juju-services
rm -rf /root/cdk /var/lib/juju/ /opt/calicoctl /var/log/juju/*
rm -rf /home/ubuntu/config*
