今の状態

作成済みであるバーチャルホスト上のDockerホストのステータスが非ACTIVEとなっています。

%docker-machine ls
NAME      ACTIVE   DRIVER       STATE     URL   SWARM   DOCKER    ERRORS
default   -        virtualbox   Stopped                 Unknown

バーチャルボックス上のDockerデーモンを起動させる

%docker-machine start default
Starting "default"...
(default) Check network to re-create if needed...
(default) Waiting for an IP...
Machine "default" was started.
Waiting for SSH to be available...
Detecting the provisioner...
Started machines may have new IP addresses. You may need to re-run the `docker-machine env` command.

バーチャルボックス上のDockerデーモンの起動確認

%docker-machine ls                 
NAME      ACTIVE   DRIVER       STATE     URL                         SWARM   DOCKER      ERRORS
default   *        virtualbox   Running   tcp://192.168.99.100:2376           v19.03.12

バーチャルボックス上のDockerデーモンへ接続する

%docker-machine env          
export DOCKER_TLS_VERIFY="1"
export DOCKER_HOST="tcp://192.168.99.100:2376"
export DOCKER_CERT_PATH="/Users/da-shibata/.docker/machine/machines/default"
export DOCKER_MACHINE_NAME="default"
# Run this command to configure your shell: 
# eval $(docker-machine env)

上記の環境変数を、下記のcommandでまとめて設定することで接続される。

%eval $(docker-machine env)

バーチャルボックス上のDockerホストでApacheのコンテナを起動する

-dを付け忘れるとFOREGROUNDで実行されてしまうので、こうやってプロンプトが返ってこなくなる。

Apacheの起動を確認する

起動はOK
$PWDを指定したことで、カレントディレクトリが公開されてしまいましたが、実際に公開するときはホスト側のディレクトリを選びましょう。

※ここからはdocker machineの操作ではありません。ホストOSでApacheコンテナを起動している例です。

ログを確認する方法

Apacheをバックグラウンドで起動する

docker logs コマンドを実行する

docker logs の後にコンテナIDかコンテナ名を指定して実行する。
