我使用以下方式在后台运行容器:
docker run --restart always --name lnmp -v /Users/gedongdong/web:/var/www/ -itd lnmp
docker 文件:
FROM alpine:edge
LABEL <a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="c3a2b6b7abacb1fea4a6a7acada4a7acada4f1f3f2f383f2f5f0eda0acae" rel="noreferrer noopener nofollow">[email protected]</a>
RUN mkdir -p /run/nginx && mkdir -p /shell
RUN echo http://mirrors.aliyun.com/alpine/edge/main > /etc/apk/repositories && \
echo http://mirrors.aliyun.com/alpine/edge/community >> /etc/apk/repositories && \
apk update && apk add --no-cache nginx
COPY vhosts.conf /etc/nginx/conf.d/
COPY start.sh /shell
RUN chmod -R 777 /shell
EXPOSE 80 443 6379
CMD ["/shell/start.sh"]
开始.sh:
nginx -c /etc/nginx/nginx.conf
tail -f /dev/null
vhosts.conf:
server {
listen 80;
server_name docker.test;
root /var/www;
index index.html;
}
当我使用docker ps -a时:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
3a3910c0dc29 lnmp "/shell/start.sh" 16 minutes ago Restarting (1) 50 seconds ago lnmp
docker ps -a 为什么我的容器总是重新启动？
最佳答案
将 #!/bin/sh 添加到 start.sh 文件
#!/bin/sh
nginx -c /etc/nginx/nginx.conf
tail -f /dev/null
为什么容器总是重新启动:
如Henry在他的评论中指出，您的设置 --restart always 告诉了这一点。一般来说，请记住，当容器的 PID 1 停止/崩溃时，容器就会退出。例如，您的容器显示如下内容:
(请注意 PID 1 行，这是问题所在)
docker container exec -it lnmp top -n 1 -b
