## 普通用户安装

```shell
sudo apt install uidmap
containerd-rootless-setuptool.sh install
containerd-rootless-setuptool.sh check
nerdctl --version
```

## 镜像加速

为containerd配置镜像加速（docker）
参考：解决镜像加速问题

1、编辑/etc/containerd/config.toml文件，插入如下 config_path：

[plugins."io.containerd.grpc.v1.cri".registry]
      config_path = "/etc/containerd/certs.d"

2、在步骤1中指定的 **config_path **路径中创建 docker.io/hosts.toml 文件

server = "https://docker.io"
[host."https://docker.m.daocloud.io"]
  capabilities = ["pull", "resolve"]
 
[host."https://reg-mirror.qiniu.com"]
  capabilities = ["pull", "resolve"]

# registry.k8s.io镜像加速
mkdir -p /etc/containerd/certs.d/registry.k8s.io
tee /etc/containerd/certs.d/registry.k8s.io/hosts.toml << 'EOF'
server = "https://registry.k8s.io"
 
[host."https://k8s.m.daocloud.io"]
  capabilities = ["pull", "resolve", "push"]
EOF
 
# docker.elastic.co镜像加速
mkdir -p /etc/containerd/certs.d/docker.elastic.co
tee /etc/containerd/certs.d/docker.elastic.co/hosts.toml << 'EOF'
server = "https://docker.elastic.co"
 
[host."https://elastic.m.daocloud.io"]
  capabilities = ["pull", "resolve", "push"]
EOF
 
# gcr.io镜像加速
mkdir -p /etc/containerd/certs.d/gcr.io
tee /etc/containerd/certs.d/gcr.io/hosts.toml << 'EOF'
server = "https://gcr.io"
 
[host."https://gcr.m.daocloud.io"]
  capabilities = ["pull", "resolve", "push"]
EOF
 
# ghcr.io镜像加速
mkdir -p /etc/containerd/certs.d/ghcr.io
tee /etc/containerd/certs.d/ghcr.io/hosts.toml << 'EOF'
server = "https://ghcr.io"
 
[host."https://ghcr.m.daocloud.io"]
  capabilities = ["pull", "resolve", "push"]
EOF
 
# k8s.gcr.io镜像加速
mkdir -p /etc/containerd/certs.d/k8s.gcr.io
tee /etc/containerd/certs.d/k8s.gcr.io/hosts.toml << 'EOF'
server = "https://k8s.gcr.io"
 
[host."https://k8s-gcr.m.daocloud.io"]
  capabilities = ["pull", "resolve", "push"]
EOF
 
# mcr.m.daocloud.io镜像加速
mkdir -p /etc/containerd/certs.d/mcr.microsoft.com
tee /etc/containerd/certs.d/mcr.microsoft.com/hosts.toml << 'EOF'
server = "https://mcr.microsoft.com"
 
[host."https://mcr.m.daocloud.io"]
  capabilities = ["pull", "resolve", "push"]
EOF
 
# nvcr.io镜像加速
mkdir -p /etc/containerd/certs.d/nvcr.io
tee /etc/containerd/certs.d/nvcr.io/hosts.toml << 'EOF'
server = "https://nvcr.io"
 
[host."https://nvcr.m.daocloud.io"]
  capabilities = ["pull", "resolve", "push"]
EOF
 
# quay.io镜像加速
mkdir -p /etc/containerd/certs.d/quay.io
tee /etc/containerd/certs.d/quay.io/hosts.toml << 'EOF'
server = "https://quay.io"
 
[host."https://quay.m.daocloud.io"]
  capabilities = ["pull", "resolve", "push"]
EOF
 
# registry.jujucharms.com镜像加速
mkdir -p /etc/containerd/certs.d/registry.jujucharms.com
tee /etc/containerd/certs.d/registry.jujucharms.com/hosts.toml << 'EOF'
server = "https://registry.jujucharms.com"
 
[host."https://jujucharms.m.daocloud.io"]
  capabilities = ["pull", "resolve", "push"]
EOF
 
# rocks.canonical.com镜像加速
mkdir -p /etc/containerd/certs.d/rocks.canonical.com
tee /etc/containerd/certs.d/rocks.canonical.com/hosts.toml << 'EOF'
server = "https://rocks.canonical.com"
 
[host."https://rocks-canonical.m.daocloud.io"]
  capabilities = ["pull", "resolve", "push"]
