IMPORTANT NOTE: We are no longer hosting the communal Docker daemon. You should get docker from here.

Docker Workshop Notes

Installing Docker

Windows

Open PowerShell and paste this:

Invoke-WebRequest -Uri "https://horner.tj/dockerwin" -OutFile "docker.exe"; $env:DOCKER_HOST = "tcp://40.84.236.92:1234"

Linux

Open a terminal and paste this:

wget https://horner.tj/docker && chmod +x docker && export DOCKER_HOST=tcp://40.84.236.92:1234

macOS

Open a terminal and paste this:

curl https://horner.tj/dockermac -o docker && chmod +x docker && export DOCKER_HOST=tcp://40.84.236.92:1234

Invoking Docker

./docker [your-command]

If you get an error that looks like this:

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

Then run the following command:

• Windows: $env:DOCKER_HOST = "tcp://40.84.236.92:1234"
• Linux/macOS: export DOCKER_HOST=tcp://40.84.236.92:1234

This will tell Docker to connect to our hosted Docker daemon.

Testing Docker

To see if Docker works, run the command ./docker info. If you don't get any errors, then you're good to go for the rest of this demo!
