ubuntu@ip-172-26-3-207:~$ jq
jq - commandline JSON processor [version 1.5-1-a5b5cbe]
Usage: jq [options] <jq filter> [file...]
jq is a tool for processing JSON inputs, applying the
given filter to its JSON text inputs and producing the
filter's results as JSON on standard output.
The simplest filter is ., which is the identity filter,
copying jq's input to its output unmodified (except for
formatting).
For more advanced filters see the jq(1) manpage ("man jq")
and/or https://stedolan.github.io/jq
Some of the options include:
-c compact instead of pretty-printed output;
-n use `null` as the single input value;
-e set the exit status code based on the output;
-s read (slurp) all inputs into an array; apply filter to it;
-r output raw strings, not JSON texts;
-R read raw strings, not JSON texts;
-C colorize JSON;
-M monochrome (don't colorize JSON);
-S sort keys of objects on output;
--tab use tabs for indentation;
--arg a v set variable $a to value <v>;
--argjson a v set variable $a to JSON value <v>;
--slurpfile a f set variable $a to an array of JSON texts read from <f>;
See the manpage for more options.

If you would like to use Docker as a non-root user, you should now consider
adding your user to the "docker" group with something like:
sudo usermod -aG docker your-user
Remember that you will have to log out and back in for this to take effect!
WARNING: Adding a user to the "docker" group will grant the ability to run
containers which can be used to obtain root privileges on the
docker host.
Refer to https://docs.docker.com/engine/security/security/#docker-daemon-attack-surface
for more information.

- docker-compose 실습
wordpress와 mysql이라는 이름으로 도커 컨테이너 서비스를 띄우겠다는 것이고, 아래와 같이 mysql의 environment를 설정해주면 위에서처럼 mysql에 접속해서 데이터베이스 만들고 이러는 과정이 필요가 없다. 그리고 docker-compose는 여러 서비스들을 같이 만들경우 자체적으로 네트워크를 만들기 때문에 굳이 네트워크를 생성하고 그 네트워크에 속하라는 설정을 안해줘도 된다.
mysql이 뜨기전에 wordpress가 뜨면 mysql이 없다고해서 wordpress가 죽게되는데 아래와 같이 restart: always 명령어를 넣어주면 mysql이 살아있을때까지 리스타트를 계속해서 wordpress를 생성해주게 된다.
