aws linux docker proxy

1. Create a systemd drop-in directory for the docker service:
2. $ sudo mkdir -p /etc/systemd/system/docker.service.d
3. Create a file named /etc/systemd/system/docker.service.d/http-proxy.conf that adds the HTTP_PROXY environment variable:If you are behind an HTTPS proxy server, set the HTTPS_PROXY environment variable:Multiple environment variables can be set; to set both a non-HTTPS and a HTTPs proxy;
4. [Service] Environment="HTTP_PROXY=http://proxy.example.com:80" Environment="HTTPS_PROXY=https://proxy.example.com:443"
5. [Service] Environment="HTTPS_PROXY=https://proxy.example.com:443"
6. [Service] Environment="HTTP_PROXY=http://proxy.example.com:80"
7. If you have internal Docker registries that you need to contact without proxying you can specify them via the NO_PROXY environment variable.
   • IP address prefix (1.2.3.4)
   • Domain name, or a special DNS label (*)
   • A domain name matches that name and all subdomains. A domain name with a leading “.” matches subdomains only. For example, given the domains foo.example.com and example.com:
     • example.com matches example.com and foo.example.com, and
     • .example.com matches only foo.example.com
   • A single asterisk (*) indicates that no proxying should be done
   • Literal port numbers are accepted by IP address prefixes (1.2.3.4:80) and domain names (foo.example.com:80)
   Config example:
8. [Service] Environment="HTTP_PROXY=http://proxy.example.com:80" ##Environment="HTTPS_PROXY=https://proxy.example.com:443" -> TLS Error 발생하여 주석처리 하고 정상 작동 Environment="NO_PROXY=localhost,127.0.0.1,docker-registry.example.com,.corp"
9. The NO_PROXY variable specifies a string that contains comma-separated values for hosts that should be excluded from proxying. These are the options you can specify to exclude hosts:
10. Flush changes and restart Docker
11. $ sudo systemctl daemon-reload $ sudo systemctl restart docker
12. Verify that the configuration has been loaded and matches the changes you made, for example:
13. $ sudo systemctl show --property=Environment docker Environment=HTTP_PROXY=http://proxy.example.com:80 HTTPS_PROXY=https://proxy.example.com:443 NO_PROXY=localhost,127.0.0.1,docker-registry.example.com,.corp
