containerd配置镜像加速

• 配置文档:github.com/containerd/…
• 镜像源收集地址:github.com/DaoCloud/pu…

1.修改/etc/containerd/config.toml配置文件

指定config_path的目录

[root@master certs.d]# grep -A 1 '\[plugins\.\"io\.containerd\.grpc\.v1\.cri\"\.registry\]'  /etc/containerd/config.toml
    [plugins."io.containerd.grpc.v1.cri".registry]
      config_path = "/etc/containerd/certs.d"

2.创建目录

mkdir -p  /etc/containerd/certs.d

3.添加对应的镜像加速配置

# docker hub镜像加速
mkdir -p /etc/containerd/certs.d/docker.io
cat > /etc/containerd/certs.d/docker.io/hosts.toml << EOF

[host."https://k8s-gcr.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"]

EOF

4.重启containerd

systemctl restart containerd
