Docker 忽略入口点

Question

有一些奇怪的错误运行以下docker命令：

docker run -d \
    --network="etcd" \
    --ip 172.28.0.4 \
    -v $(pwd)/etcd01:/etc/ssl/certs \
    -p 4001:4001 -p 2380:2380 -p 2379:2379 \
    --hostname etcd01 \
    --name etcd01 quay.io/coreos/etcd:latest \
    -name etcd01 \
    -advertise-client-urls http://172.28.0.4:2379,http://172.28.0.4:4001 \
    -listen-client-urls http://0.0.0.0:2379,http://0.0.0.0:4001 \
    -initial-advertise-peer-urls http://172.28.0.4:2380 \
    -listen-peer-urls http://0.0.0.0:2380 \
    -initial-cluster etcd01=http://172.28.0.4:2380,etcd01=http://172.28.0.2:2380,etcd02=http://172.28.0.3:2380 \
    -initial-cluster-state new

etcd's Dockerfile. And the docker docs 中定义了一个 ENTRYPOINT 表示图像名称之后的所有内容都作为参数传递给入口点。那为什么不呢？

我收到如下错误：docker: Error response from daemon: oci runtime error: container_linux.go:247: starting container process caused "exec: \"-name\": executable file not found in $PATH".

当然-name不是命令。它应该是 etcd.

的第一个参数

覆盖容器命令的问题。要执行此操作，我建议您稍微修改一下命令：

docker run -d \
    --network="etcd" \
    --ip 172.28.0.4 \
    -v $(pwd)/etcd01:/etc/ssl/certs \
    -p 4001:4001 -p 2380:2380 -p 2379:2379 \
    --hostname etcd01 \
    --name etcd01 quay.io/coreos/etcd:latest \
    etcd \
    -name etcd01 \
    -advertise-client-urls http://172.28.0.4:2379,http://172.28.0.4:4001 \
    -listen-client-urls http://0.0.0.0:2379,http://0.0.0.0:4001 \
    -initial-advertise-peer-urls http://172.28.0.4:2380 \
    -listen-peer-urls http://0.0.0.0:2380 \
    -initial-cluster etcd01=http://172.28.0.4:2380,etcd01=http://172.28.0.2:2380,etcd02=http://172.28.0.3:2380 \
    -initial-cluster-state new

Docker ignores ENTRYPOINT

docker

etcd
