docker-machine env をするとエラー
eval "$(docker-machine env vm01)"
Error checking TLS connection: Error checking and/or regenerating the certs: There was an error validating certificates for host "111.222.333.444:2376": x509: certificate is valid for 111.222.333.444, not 555.666.777.888
You can attempt to regenerate them using 'docker-machine regenerate-certs [name]'.
Be advised that this will trigger a Docker daemon restart which might stop running containers.
- vm01はdocker-machineの名前
- 111.222.333.444(仮)は最初にGCPのインスタンスに作ったdocker-machineのIP
- 555.666.777.888(仮)はGCPのインスタンスのIP変更後のIP
docker-machine ls で確認
$ docker-machine ls

これで大丈夫そう。
