GitLab CI/CD 部署Django项目

nginx

• 重写一段nginx的配置
• 在打镜像的时候，ADD到新的镜像中去
• 这里要注意指定端口号

server {
    listen 3456;
    charset utf-8;
    client_max_body_size 75M;

    location /static {
        alias /home/project/static/;
    }

    location / {
        uwsgi_pass 0.0.0.0:8000;
        include /etc/nginx/uwsgi_params;
    }
}

uwsgi

• Django的uwsgi配置文件
• 在Django项目文件中，一起复制到镜像中
• 注意端口暴露方式，这会影响访问结果

[uwsgi]

chdir = /home/project
module = test_2.wsgi:application
wsgi-file = /home/project/uwsgi.ini
pyenv = /usr/local/python3/bin/python3
log-format = [%(ctime)] %(method) %(status) %(uri)
;daemonize = /home/project/logs/uwsgi.log
thread = 8
uid = nginx
gid = nginx
vacuum = true
master = true
processes = 8
max-requests = 5000
socket = 0.0.0.0:8000

run.sh

• run一个容器时候执行的脚本
• 在放入镜像中后，需要修改sh文件的执行权限
• 复制文件的时候，注意文件所在位置

echo "服务启动中..."
nginx
/usr/local/python3/bin/uwsgi --ini /home/project/uwsgi.ini
echo "服务启动成功..."
sleep 3600h  # 只是设置了等待时间

docker

• 如果需要修改Python版本，直接修改所有Python-3.8.10
• 也可以先生成一个基础镜像，再一点点丰富它

• Docker登录的设置Docker的配置文件
• 部署的时候，需要先配置免密码登录
