文件未绑定安装到docker-compose

Question

我正在运行docker compose测试；我的堆栈中执行实际测试的部分是以下服务

  tester:
    image: tutum/curl:latest
    volumes:
      - ./ci/wait-for-it.sh:/usr/local/bin/wait-for-it.sh
      - ./webhooks:/app/webhooks
    depends_on:
      - sut
    command: ["wait-for-it.sh", "sut:8080", "-t", "240", "--", "sh", "pytest /app/webhooks"]

命令失败如下：

ERROR: for 0114c9206690_alerta-_tester_1  Cannot start service tester: OCI runtime create failed: container_linux.go:349: starting container process caused "exec: \"wait-for-it.sh\": executable file not found in $PATH": unknown

ERROR: for tester  Cannot start service tester: OCI runtime create failed: container_linux.go:349: starting container process caused "exec: \"wait-for-it.sh\": executable file not found in $PATH": unknown

正在装载的文件确实存在：

▶ ls docker-compose.test.yaml
docker-compose.test.yaml

Workspace/systems-utils/  alerta_dev_infra ✗                                                                         1d ⚑ ◒
▶ ls ./ci/wait-for-it.sh
./ci/wait-for-it.sh

此外，当试图将装载绑定到一个不存在的文件时，我没有得到与装载相关的错误，而是得到了与上面相同的错误

  tester:
    image: tutum/curl:latest
    volumes:
      - ./ci/foofile.sh:/usr/local/bin/wait-for-it.sh
      - ./webhooks:/app/webhooks
    depends_on:
      - sut
    command: ["wait-for-it.sh", "sut:8080", "-t", "240", "--", "sh", "pytest /app/webhooks"]

$ docker-compose -f docker-compose.test.yaml up -d

ERROR: for tester  Cannot start service tester: OCI runtime create failed: container_linux.go:349: starting container process caused "exec: \"wait-for-it.sh\": executable file not found in $PATH": unknown
ERROR: Encountered errors while bringing up the project.

我错过了什么？

编辑：关于提到的PATH问题，这里是：

▶ docker run -it tutum/curl:latest printenv
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
HOSTNAME=1f3090676fa0
TERM=xterm
HOME=/

此外，测试仪的服务配置与本项目完全相同，运行良好。

关于权限问题：

Workspace/systems-utils/alerta-workable  alerta_dev_infra ✗                                                                        1d ⚑ ◒  ⍉
▶ ls -al ./ci/wait-for-it.sh
-rwxr-xr-x  1 pkaramol  staff   5.1K Sep  6 22:02 ./ci/wait-for-it.sh

Answer 1

看起来它找不到“在$PATH中的可执行文件”

那么，让我们试着在<代码>上设置可执行权限/ci/等待。sh文件：

$ chmod +x ./ci/wait-for-it.sh

Answer 2

错误消息很容易解释-等待它。sh不在$PATH上。

您需要将命令添加到$PATH或将命令更改为

command: ["/usr/local/bin/wait-for-it.sh", "sut:8080", "-t", "240", "--", "sh", "pytest /app/webhooks"]

另请参阅此问题的公认答案，了解为什么/usr/local/bin可能不在路径中。
