Docker Compose部署Nginx的方法步骤

使用Docker Compose部署Nginx，创建docker-compose.yaml：

[root@192 ~]# vim docker-compose.yaml

输入以下内容：

version: 3 services: nginx: container_name: nginx image: nginx restart: always ports: – 8080:80 privileged: true networks: – mynginx networks: mynginx: driver: bridge

基于docker-compose.yaml创建并启动容器：

[root@192 ~]# docker compose up [+] Running 7/7 ⠿ nginx Pulled 20.5s ⠿ 5eb5b503b376 Pull complete 12.6s ⠿ 1ae07ab881bd Pull complete 14.8s ⠿ 78091884b7be Pull complete 14.9s ⠿ 091c283c6a66 Pull complete 15.0s ⠿ 55de5851019b Pull complete 15.1s ⠿ b559bad762be Pull complete 15.2s [+] Running 2/2 ⠿ Network root_mynginx Created 0.3s ⠿ Container nginx Created 1.8s Attaching to nginx nginx | /docker-entrypoint.sh: /docker-entrypoint.d/ is not empty, will attempt to perform configuration nginx | /docker-entrypoint.sh: Looking for shell scripts in /docker-entrypoint.d/ nginx | /docker-entrypoint.sh: Launching /docker-entrypoint.d/10-listen-on-ipv6-by-default.sh nginx | 10-listen-on-ipv6-by-default.sh: info: Getting the checksum of /etc/nginx/conf.d/default.conf nginx | 10-listen-on-ipv6-by-default.sh: info: Enabled listen on IPv6 in /etc/nginx/conf.d/default.conf nginx | /docker-entrypoint.sh: Launching /docker-entrypoint.d/20-envsubst-on-templates.sh nginx | /docker-entrypoint.sh: Launching /docker-entrypoint.d/30-tune-worker-processes.sh nginx | /docker-entrypoint.sh: Configuration complete; ready for start up nginx | 2022/02/13 03:43:39 [notice] 1#1: using the “epoll” event method nginx | 2022/02/13 03:43:39 [notice] 1#1: nginx/1.21.6 nginx | 2022/02/13 03:43:39 [notice] 1#1: built by gcc 10.2.1 20210110 (Debian 10.2.1-6) nginx | 2022/02/13 03:43:39 [notice] 1#1: OS: Linux 3.10.0-1160.el7.x86_64 nginx | 2022/02/13 03:43:39 [notice] 1#1: getrlimit(RLIMIT_NOFILE): 1048576:1048576 nginx | 2022/02/13 03:43:39 [notice] 1#1: start worker processes nginx | 2022/02/13 03:43:39 [notice] 1#1: start worker process 31

关闭防火墙：

[root@192 ~]# systemctl stop firewalld

本地浏览器可以访问，说明Nginx部署成功了。

Docker也可以查到Docker Compose拉取的镜像和创建的容器。

[root@192 ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE nginx latest c316d5a335a5 2 weeks ago 142MB lazyteam/lazydocker latest 3b572700e20d 10 months ago 69.9MB portainer/portainer latest 580c0e4e98b0 11 months ago 79.1MB openjdk 8-jdk-alpine a3562aa0b991 2 years ago 105MB [root@192 ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES e31945577104 nginx “/docker-entrypoint.…” 7 minutes ago Up 7 minutes 0.0.0.0:8080->80/tcp, :::8080->80/tcp nginx

后台up（防火墙需要先开启，不然会报错）：

[root@192 ~]# systemctl start firewalld [root@192 ~]# docker compose up -d [+] Running 1/1 ⠿ Container nginx Started

关闭服务：

[root@192 ~]# docker compose stop nginx [+] Running 1/1 ⠿ Container nginx Stopped

启动服务：

[root@192 ~]# docker compose start nginx [+] Running 1/1 ⠿ Container nginx Started
