Vagrant Docker Docker-compose で オンプレミスのビジネスチャット RocketChat 導入

Qiita内でも調べてみたけど、１つの記事ですべて解決できなかったので投稿。
具体的に詰まったのは、

• http://localhost:3000 につながらない
• ERROR: OPLOG / REPLICASET IS REQUIRED TO RUN ROCKET.CHAT, MORE INFORMATION AT: | ➔ | https://go.rocket.chat/i/oplog-required と出てうまくDocker-composeが起動できてない

以下、自分用のOnenoteよりコピペなので見づらいですが

vagrant, docker, docker-compose, windows10, install, rocketchat

試したのはWindows10で

Vagrant install

VirtualBox+Vagrantで楽々Docker環境構築（Windows）
2019/7現在：上記のままやるとエラー。http://localhost:3000 で繋がらない
mongo replica の設定が必要らしいので、このノートページの最下部を参照に！

VirtualBox install

Vagrant install

Vagrantプラグインのインストール

// Guest Additions の手動再インストールの手間をなくすプラグイン　おすすめとのこと
PS C:\dokoka> vagrant plugin install vagrant-vbguest
// プロキシ使う場合はこれも
PS C:\dokoka> vagrant plugin install vagrant-proxyconf

dockerVM @ vagrant

Dockerコンテナ導入

PS C:\dokoka> cd <適当なフォルダ>
PS C:\dokoka> git clone https://github.com/sesela/vagrant-ubuntu-for-docker.git
PS C:\dokoka> cd vagrant-ubuntu-for-docker
PS C:\dokoka\vagrant-ubuntu-for-docker> vagrant up

// SSH接続
PS C:\dokoka\vagrant-ubuntu-for-docker> vagrant ssh
// USER/PWD は vagrant:vagrant

// サービス終了
PS C:\dokoka\vagrant-ubuntu-for-docker> vagrant halt

setup Docker Compose & RocketChat @ dockerVM

Instead of using the standard Docker commands, you may wish for a bit more automated management of the deployment. This is where the use of Docker-compose may come in handy.
• Make sure you have Docker and Docker-compose installed and operational.
• Create docker-compose.yml based on our example. This is the ONLY file you will need. You can create this file on your own machine by copy and pasting the content.
• Edit image: rocketchat/rocket.chat:develop to specify which image you wish to use (see section Docker Images Available )
• Edit ROOT_URL to match your domain name or IP address

You can download our docker-compose.yaml:

curl -L https://raw.githubusercontent.com/RocketChat/Rocket.Chat/develop/docker-compose.yml -o docker-compose.yml

Start the mongodb server by:

docker-compose up -d mongo

The first time you start mongo, you’ll also need to initialize it before being able to use Rocket.Chat. Ensure that mongo is in the running state, then:

docker-compose up -d mongo-init-replica

Mongo supports 24 x 7 operations and live backup. You should not need to restart it too frequently. See mongodb documentations for proper operation and management of a mongo server.
Once you’re sure that mongodb is up and running:

docker-compose up -d rocketchat

Optionally, if you want to manage your messages and configuration information, edit the file again to uncomment the volume mounts. Make sure you have a datasubdirectory to mount and store the data.
Optionally, if you want a bot, so you don’t have to talk to yourself, after you’ve created an admin user and also a bot user, edit the file docker-compose.yml again to change the variables ROCKETCHAT_USER and ROCKETCHAT_PASSWORD in the hubot section and then start up hubot:

docker-compose up -d hubot

To update the rocketchat docker image to the latest version, you can use the following commands. Your data should not be affected by this, since it’s located in the mongo image.

docker pull rocketchat/rocket.chat:develop
docker-compose stop rocketchat
docker-compose rm rocketchat
docker-compose up -d rocketchat
