Docker+Python3+Seleniumで「chromedriver unexpectedly exited. Status code was: 255」

Docker上に、Python3.8ベースで環境を作り、

seleniumで試そうとしていたところ、

うまくいかない事象が起きて、

エラーが起きたのでメモを残す。

個人的な備忘録のために、

この記事に残しておく。

エラー内容メモ

コンテナ内で、

seleniumを立ち上げる中で、

chromedriverの処理として、

try:
    self.driver = webdriver.Chrome(options=chrome_options)
except Exception as e:
    print(f"An error occurred: {str(e)}")

この部分でエラーを確認すると、

An error occurred:
Message:
Service /root/.cache/selenium/chromedriver/linux64/118.0.5993.70/chromedriver
unexpectedly exited.
Status code was: 255

このようなエラーが発生。

以下のコードを作って実行。
