嘗試在insercure泊塢窗註冊表添加到我在大廳任務運行DIND圖像：我試圖通過運行開始我的任務設置在泊塢窗功能於碼頭工人形象碼頭工人守護不安全註冊表
：
export DOCKER_OPTS="$DOCKER_OPTS --insecure-registry=${INSECURE_REG}"
，並試圖轉起來時，守護進程和組成：
docker daemon --insecure-registry=${INSECURE_REG} &
docker-compose up
但是任務的錯誤：服務器給HTTP響應HTTPS客戶端，並沒有這樣的圖像
整個任務看起來是這樣的（基本上是在一個碼頭工人，撰寫結束DIND容器中執行一個shell腳本）：
# Connect to insecure docker registry:
export DOCKER_OPTS="$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
