docker - Dockerfile 无法启动 CMD 脚本

问题描述

我在 Dockerfile 中有这个：

FROM node:alpine

COPY seed.sh /
RUN chmod +x /seed.sh
RUN apk add --no-cache bash

CMD pwd; ls -al; cat seed.sh; ./seed.sh

然后我构建 docker-compose 并启动它：

[docker-compose.yml 部分]

...
dbseeder:
  container_name: dbseeder
  build:
    context: ./db-seeder
    dockerfile: Dockerfile
  depends_on:
    - db
...

构建/运行

docker-compose build --no-cache
docker-compose up

up输出如下：

dbseeder    |
dbseeder    | echo "Seeding database..."
dbseeder    |
dbseeder    | cd seeders
dbseeder    | npx sequelize db:seed:all --url 'mysql://root:pass123@dbserver/mydb'
dbseeder    |
dbseeder    | echo "Seeding done."
dbseeder    | /bin/sh: ./seed.sh: not found

无论我做什么，都找不到seed.sh，但如您所见，它就在那里。

我究竟做错了什么？

编辑

是的，我尝试使用 '/bin/sh'

[部分向上输出]

...
dbseeder    | #!/bin/sh
dbseeder    |
dbseeder    | echo "Seeding database..."
dbseeder    |
dbseeder    | cd seeders
dbseeder    | #sequelize db:seed:all
dbseeder    | npx sequelize db:seed:all --url 'mysql://root:pass123@dbserver/mydb'
dbseeder    |
dbseeder    | echo "Seeding done."
dbseeder    | /bin/sh: ./seed.sh: not found
...
