管理 Containerd 容器: ctr 命令使用

# --address value, -a value 指定 containerd's GRPC server，默認 /run/containerd/containerd.sock

# 查看 K8S 命名空間下的鏡像
ctr -n k8s.io images ls

# 下載鏡像
ctr images pull docker.io/library/redis:alpine

# 創建 container
ctr c create docker.io/library/redis:alpine redis-container

# 查看
ctr c ls

# 后台啟動
ctr t start -d redis-container

# 查看 container
ctr t ls

# 查看 k8s 中正在運行的容器
ctr -n k8s.io task ls

# 打tag
ctr images tag docker.io/library/redis:alpine harbor.junengcloud.com/tmp/redis:alpine

# push 上傳鏡像
ctr images push harbor.junengcloud.com/tmp/redis:alpine
# 注意可能會出現 ctr: content digest sha256:xxxxxx  not found，解決辦法，下載完整的
ctr image pull --all-platforms docker.io/library/redis:alpine
ctr images rm harbor.junengcloud.com/tmp/redis:alpine
ctr images tag docker.io/library/redis:alpine harbor.junengcloud.com/tmp/redis:alpine

ctr images push harbor.junengcloud.com/tmp/redis:alpine

# 離線導入 docker 鏡像，在其他 docker 上導出， containerd 鏡像導入
docker save -o rabbitmq_3.7.8.tar harbor.junengcloud.com/rabbitmq/rabbitmq:3.7.8
ctr images import rabbitmq_3.7.8.tar
ctr images ls -q
