第10章 外部ネットワークアクセス用のプロキシーの設定

手順

1. 既存のシークレットを YAML ファイルとして保存します。

   $ oc -n stackrox get secret proxy-config \
     -o go-template='{{index .data "config.yaml" | \
     base64decode}}{{"\n"}}' > /tmp/proxy-config.yaml

2. YAML 設定ファイルで変更するフィールドを編集します。以下に例を示します。

       # # NOTE: Both central and scanner should be restarted if this secret is changed.
       # # While it is possible that some components will pick up the new proxy configuration
       # # without a restart, it cannot be guaranteed that this will apply to every possible
       # # integration etc.
       # url: http://proxy.name:port
       # username: username
       # password: password
       # # If the following value is set to true, the proxy wil NOT be excluded for the default hosts:
       # # - *.stackrox, *.stackrox.svc
       # # - localhost, localhost.localdomain, 127.0.0.0/8, ::1
       # # - *.local
       # omitDefaultExcludes: false
       # excludes:  # hostnames (may include * components) for which you do not
       # # want to use a proxy, like in-cluster repositories.
       # - some.domain
       # # The following configuration sections allow specifying a different proxy to be used for HTTP(S) connections.
       # # If they are omitted, the above configuration is used for HTTP(S) connections as well as TCP connections.
       # # If only the `http` section is given, it will be used for HTTPS connections as well.
       # # Note: in most cases, a single, global proxy configuration is sufficient.
       # http:
       #   url: http://http-proxy.name:port
       #   username: username
       #   password: password
       # https:
       #   url: http://https-proxy.name:port
       #   username: username
       #   password: password

3. 変更を保存した後、次のコマンドを実行してシークレットを置き換えます。

   $ oc -n stackrox create secret generic proxy-config \
     --from-file=config.yaml=/tmp/proxy-config.yaml -o yaml --dry-run | \
     oc label -f - --local -o yaml app.kubernetes.io/name=stackrox | \
     oc apply -f -
