从Docker Compose内部构建Dockerfile

Question

所以我尝试按照以下说明进行操作：

https://github.com/open-forest/sendy

我正在使用Portainer并尝试运行Sendy容器(时事通讯软件(。我没有用它运行MySQL映像，而是使用我的外部托管数据库。

在我的服务器上，我将项目数据保存在：/var/docker/project-name。如果我需要从一开始就将数据带入容器，我会使用这种结构进行绑定挂载。

因此，对于这个项目，在项目名称文件夹中，我有sendy-6.0.2.zip和这个Dockerfile：(这个文件是通过上面链接上的说明提供的(

这是我的Docker Compose文件：

version: '3.7'
services:
project-sendy:
container_name: project-sendy
image: sendy:6.0.2
build: 
dockerfile: var/docker/project-sendy/Dockerfile
restart: unless-stopped
networks:
- proxy
- default
labels:
- "traefik.enable=true"
- "traefik.docker.network=proxy"
- "traefik.http.routers.project-secure.entrypoints=websecure"
- "traefik.http.routers.project-secure.rule=Host(`project.com`)"
environment:
SENDY_PROTOCOL: https
SENDY_FQDN: project.com
MYSQL_HOST: db-host-name-here
MYSQL_DATABASE: db-name-here
MYSQL_USER: db-user-name-here
MYSQL_PASSWORD: db-password-here
SENDY_DB_PORT: db-port-here

networks:
proxy:
external: true  

当我尝试部署时，我得到：

failed to deploy a stack: project-sendy Pulling project-sendy 
Error could not find /data/compose/126/var/docker/project-sendy: 
stat /data/compose/126/var/docker/project-sendy: no such file or directory

Answer 1

下面是我所做的。

我的cron和artifacts文件夹与Dockerfile位于同一目录中。在Dockerfile中查找以下行：

COPY artifacts/docker-entrypoint.sh /usr/local/bin/

下面写着：

RUN chmod +x /usr/local/bin/docker-entrypoint.sh

否则你会得到这个错误：

Starting Error response from daemon: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: exec: "/usr/local/bin/docker-entrypoint.sh": permission denied: unknown 

然后用构建

docker build -t sendy:6.0.2 .

然后你的图像将显示在门户中。

然后，您可以删除docker compose文件中的构建部分，然后点击deploy。它现在对我有效。
