Get it done with just one line of command:
docker run \ --name nginx-health-web-pc \ -d -p 6800:80 \ -v /usr/docker/nginx/html:/usr/share/nginx/html \ nginx
It’s a joy to run and start~~~~~At this time, the front end suddenly came over and said: "You need to add a configuration to your nginx", and by the way, he also told you: " "So-and-so was configured like this before",
You can't refuse if you are competitive at this time, but it still takes some effort to actually configure it. Under normal circumstances, docker is configured when it starts, as long as the configuration file Just mount the directory, which is simple and convenient. However, nginx first loads a main configuration file nginx.conf, and then loads the sub-configuration files in the conf.d directory in nginx.conf (usually at least one default.conf file). This is a lot more troublesome than mounting a directory alone, but it's not difficult as long as you have a clear idea.
Let’s look at the mounted command first:
Command to start docker
docker run \ --name mynginx \ -d -p 80:80 \ -v /usr/docker/mynginx/html:/usr/share/nginx/html \ -v /etc/docker/mynginx/nginx.conf:/etc/nginx/nginx.conf:ro \ -v /etc/docker/mynginx/conf.d:/etc/nginx/conf.d \ nginx
There are a few things to note here:
(1) The first "-v" is the project location, just put the project in the directory where it is mounted;
(2) The second "-v" is Mount the main configuration file "nginx.conf". Note that there is a line "include /etc/nginx/conf.d/*.conf;" in the "nginx.conf" file. This include points to the path of the sub-configuration file. This Please pay attention to the path following include and make sure there is no mistake.
(3) The third "-v" also mounts the path of the sub-configuration file in docker. Note that it must be consistent with the path pointed to by include in (2)
(4) It is important to emphasize that nginx.conf mounts a file (docker is not recommended to use this way), and conf.d mounts a directory.
Let’s start it first, and we can find that there is a problem. Because the configuration file does not exist yet.
Configuration configuration file
We find the configuration file generated when nginx is installed by the conventional method (usually under "/etc/nginx"), corresponding to the above startup command The mounting location, put the main configuration file nginx.conf into the corresponding location "/etc/docker/mynginx/nginx.conf", and put the sub-configuration file "default.conf" into "/etc/docker/mynginx/conf. d" directory
Re-run the startup command,found that it is ready. At this point, the files in docker can be configured at will, which is exactly the same as the native installation
Thinking: There must be one idea when configuring: the mounted file must be loaded into the docker process when running! This way there is less confusion.
