Red Hat Summit3.3. 証明機関を信頼するようにDockerを設定する
Dockerでは、カスタムcertsを/etc/docker/certs.d/に、ホスト名のプライベートレジストリと同じ名前のディレクトリにインストールする必要があります。また、証明書の名前がca.crtであることも必要です。その方法をご紹介します。
rootCAファイルをコピーします。
$ cp tmp/rootCA.pem /etc/docker/certs.d/reg.example.com/ca.crtrootCA.pemファイルをコピーすると、
docker loginが正常に認証され、リポジトリへのプッシュが成功するはずです。$ sudo docker push reg.example.com/kbrwn/hello The push refers to a repository [reg.example.com/kbrwn/hello] 5f70bf18a086: Layer already exists e493e9cb9dac: Pushed 1770dbc4af14: Pushed a7bb4eb71da7: Pushed 9fad7adcbd46: Pushed 2cec07a74a9f: Pushed f342e0a3e445: Pushed b12f995330bb: Pushed 2016366cdd69: Pushed a930437ab3a5: Pushed 15eb0f73cd14: Pushed latest: digest: sha256:c24be6d92b0a4e2bb8a8cc7c9bd044278d6abdf31534729b1660a485b1cd315c size: 7864
