SENKEN

手始めにxeyesを起動してみる

すると起動時にエラーが出た
<div class="code-block-container"><pre class="language-shell"><code class="language-shell">❯ docker run --rm -it \ 
--net host \
-e DISPLAY=$DISPLAY \
-v $HOME/.Xauthority:/root/.Xauthority \ # これはなくても起動できた
xeyes
Authorization required, but no authorization protocol specified

Error: Can't open display: :0
</code></pre></div>これで解決した

ローカルで次のコマンドを打つ
<div class="code-block-container"><pre class="language-shell"><code class="language-shell">xhost + local:
</code></pre></div>xhostが入っていない場合は
<div class="code-block-container"><pre class="language-shell"><code class="language-shell">sudo apt install -y x11-xserver-utils
</code></pre></div>でインストールできる

Docker Composeの場合は
<div class="code-block-container">
<div class="code-block-filename-container"> docker-compose.yml</div>
<pre class="language-yml"><code class="language-yml">environment:
 - DISPLAY=$DISPLAY
network_mode: "host"
</code></pre>
</div>を追記すれば良い
