Shell 腳本將 docker 圖像推送到 docker 集線器卡住

Question

I'm trying to push the docker image using the shell script, works fine till login it gets logged in but at push command it gets stuck, when I run docker push command manually it pushes the image but not using shell script.

    #!/bin/bash

    set -x #echo on

    variableA=$(docker build -f test.dockerfile --network=host --no-cache -t myrepo/docker-test . | tail -n1 | cut -d " " -f3)

    echo "$variableA"

    docker ps -a

    echo "$DOCKER_HUB_PWD" | docker login --username="$DOCKER_HUB_UNAME" --password-stdin

    tail -n1

    docker push myrepo/docker-test:latest

    tail -n1

Answer 1

它是由tail -n1引起的。

tail 命令查找輸入文件或數據 stream。

句法：

$ tail [OPTION]... [FILE]...

例子：

$ tail -n1 FILE.TXT

cat FILE.TXT | tail -n1
