title: where is hostconfig.json (Docker desktop + WSL2 environment)
body: <p>As I know, docker doesn't support any command that change port mapping after make container.<br />
  But this answer said that by changing the hostconfig.json file, I can change port mapping.</p>

  I'm using docker desktop in windows + WSL2.So path of hostconfig.json is different with other answers.<br />
  Where is hostconfig.json?<br />
  In my case, (\wsl$\docker-desktop-data\mnt\wsl\docker-desktop-data\data, /var/lib/docker(in wsl)) directories are not exist.</p>
