3. Install the hub rocketchat adapter

3.1 start a docket image

docker run -it -e ROCKETCHAT_URL="http://IP:3000" \
-e ROCKETCHAT_ROOM='' \
-e LISTEN_ON_ALL_PUBLIC=true \
-e ROCKETCHAT_USER=admin \
-e ROCKETCHAT_PASSWORD=123456 \
-e ROCKETCHAT_AUTH=password \
-e BOT_NAME=bot \
-e EXTERNAL_SCRIPTS=hubot-pugme,hubot-help \
rocketchat/hubot-rocketchat

3.2 when starting, specify the environment variable so that Hubot and others can log in to rocketchat

export ROCKETCHAT_URL="http://IP:3000" 
export ROCKETCHAT_ROOM='' 
export LISTEN_ON_ALL_PUBLIC=true
export ROCKETCHAT_USER=admin 
export ROCKETCHAT_PASSWORD=123456 
export ROCKETCHAT_AUTH=password

3.3 validation

Edit the example.coffee file in the myhubot/scripts directory, and add it as follows:

robot.hear /hi/i, (res) ->
     res.reply "hello"
robot.hear /Have you had dinner/, (res) ->
     res.send 'Only you stupid people eat'

The dialogue in rocketcha is as follows, test ok

3.4 hubot runs bash script and installs plug-in: hubot script shellcmd

cd myhubot
npm install hubot-script-shellcmd
cp -R node_modules/hubot-script-shellcmd/bash .   #seperate your shellcmd from the npm module

//Edit external-scripts.json
add 'hubot-script-shellcmd' 

After the above operations are completed, we can see that there is a bash directory, cd bash/handlers, under which there are two files: helloworld and update. In rocketchat, you can directly execute @ admin shellcmd and @ admin shellcmd helloworld to execute the above commands
