次のDockerfileを使用してください。
FROM nexylan/php-dev:7.1-alpine
COPY entrypoint.sh /
RUN chmod u+x /entrypoint.sh
ENTRYPOINT ["/entrypoint.sh"]
WORKDIR /code
CMD ["tail", "-f", "/dev/null"]
（エントリポイントはこの問題に関連する作業を行いません。）
そしてdocker-composeの定義は次のとおりです。
version: '2'
services:
data:
image: alpine
volumes:
- .:/code
console:
build: docker/php-console
volumes_from:
- data
env_file:
- .env
ローカルUbuntuコンピュータで実行している場合：
docker-compose up -d
docker-compose exec -T console ssh -o StrictHostKeyChecking=no -i tests/fixtures/ssh/key -T [email protected]
次のメッセージと共に使用されます。
Hi xXx! You've successfully authenticated, but GitHub does not provide shell access.
ただし、次のように構成されたGitLab CIランチャーインスタンスにはありません。

- docker-compose exec -T console ssh -o StrictHostKeyChecking=no -i tests/fixtures/ssh/key -T -vvv [email protected]
キーはここにあり、私のローカルキーとまったく同じですが、コマンドはリンクされておらず、ログの-vvv結果は次のようになります。

私はすでに試しました。このソリューション質問が/dev/ttyありますが、成功しませんでした！
しかもDockerイメージなので環境も同じでなければなりませんか？これが私のローカルコンピュータでは機能しますが、GitLab CIランチャーでは機能しないのはなぜですか？
ベストアンサー1
Ubuntuでは、エラーが示すように、ローカルのttyとして接続している可能性があり、GitLab CI dockerにはttyがありません。
コマンドを使用する場合
docker-compose exec -T
これによりptty割り当てが無効になるため、opensshはキーボードインタラクションパスワード入力を収集するために使用されるttyを見つけることができません。https://docs.docker.com/compose/reference/exec/ サーバーはハンドシェイク中にこれを要求したため、SSHクライアントはこれを実行しようとします。
-dオプションを使用しないため、このコマンドは既存のttyを使用します（ローカルのUbuntuシステムで機能する理由の説明があれば自動的に生成できます）。
