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

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

获取特定版本的 Bundle

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

或是

# 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

# 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

# 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

# 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
