Question

尝试将一个onsercure docker注册表添加到我在大厅任务中运行的dind图像中：

我尝试通过运行来开始我的任务：

export DOCKER_OPTS="$DOCKER_OPTS --insecure-registry=${INSECURE_REG}"

并尝试旋转守护进程并撰写：

docker daemon --insecure-registry=${INSECURE_REG} &
docker-compose up

但是任务错误：服务器向https客户端发出了http响应，没有这样的图像

整个任务看起来像这样（基本上它是在dind容器中执行的shell脚本，以docker-compose结尾）：

# Connect to insecure docker registry:
export DOCKER_OPTS="$DOCKER_OPTS --insecure-registry=${INSECURE_REG}"

# Install docker-compose:
apk add --no-cache py-pip curl
pip install docker-compose

# Verify docker registry:
curl http://${INSECURE_REG}/v2/_catalog #curl does return the expected json

sanitize_cgroups() {
  mkdir -p /sys/fs/cgroup
  mountpoint -q /sys/fs/cgroup || \
    mount -t tmpfs -o uid=0,gid=0,mode=0755 cgroup /sys/fs/cgroup

  mount -o remount,rw /sys/fs/cgroup

  sed -e 1d /proc/cgroups | while read sys hierarchy num enabled; do
    if [ "$enabled" != "1" ]; then
      # subsystem disabled; skip
      continue
    fi

    grouping="$(cat /proc/self/cgroup | cut -d: -f2 | grep "\\<$sys\\>")"
    if [ -z "$grouping" ]; then
      # subsystem not mounted anywhere; mount it on its own
      grouping="$sys"
    fi

    mountpoint="/sys/fs/cgroup/$grouping"

    mkdir -p "$mountpoint"

    # clear out existing mount to make sure new one is read-write
    if mountpoint -q "$mountpoint"; then
      umount "$mountpoint"
    fi

    mount -n -t cgroup -o "$grouping" cgroup "$mountpoint"

    if [ "$grouping" != "$sys" ]; then
      if [ -L "/sys/fs/cgroup/$sys" ]; then
        rm "/sys/fs/cgroup/$sys"
      fi

      ln -s "$mountpoint" "/sys/fs/cgroup/$sys"
    fi
  done
}

# Spin up the stack as described in docker-compose:
docker daemon --insecure-registry=${INSECURE_REG} &
docker-compose up

Answer 1

dockerd --insecure-registry=${INSECURE_REG}

使用不安全的注册表启动docker守护程序是正确的方法，即使它报告错误，它也会获得图像并成功启动它们

在docker-in-docker映像docker守护程序中设置不安全的注册表
