Note: This guide was written for Docker Community Edition 19.03.5.
To follow this guide, you will need to have Docker already installed on your local system. This guide is based on running Docker (version 19.03.5) on a fresh installation of Ubuntu 18.04 LTS.
$ sudo apt update $ sudo apt install apt-transport-https ca-certificates curl software-properties-common -y $ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add - $ sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable" $ sudo apt update $ sudo apt install docker-ce -y
This Dockerfile we suggest using is located at
https://enclave.io/install/dockerfile and based on an Ubuntu 18.04 LTS image.
$ mkdir ~/enclave-worker $ cd enclave-worker $ wget https://enclave.io/install/dockerfile
With the Dockerfile downloaded, build the Docker image.
$ sudo docker build --no-cache -t enclave .
Run the container interactively to license and start Enclave. Passing
--net=host arguments allows docker to present the tap0 interface created by Enclave inside the container out to the host operating system, without installing Enclave onto the host.
$ sudo docker run -it --privileged --net=host enclave
From within the container, license Enclave using a valid key provisioned in the Portal.
# enclave license 00000-00000-00000-00000-00000
Next, start Enclave running as a background process, detached from the terminal and shielded from the HUP signal that warns dependent processes of logout by using
nohup to run Enclave. This backgrounds Enclave and allows us to continue using the terminal.
# nohup enclave start &
Now Enclave is running in the background, detached from the terminal you can check the
status of Enclave, and
add peers as necessary.
# enclave status # enclave add ABC -d "another host running enclave"
Tip: To detach Docker from the tty of an interactive container without exiting the shell, use the escape sequence
Ctrl-q. This will switch a container running in interactive mode into daemon mode and release the terminal back to the host operating system.
While this container is running, your host operating system will be able to communicate with connected peers. Use this container to administer the Enclave network.
ifconfig check to see if the
tap0 interface is present on the host adapter, any applications on the host operating system will transparently be able to communicate with partners on the Enclave network. Use
docker ps and
docker attach to reconnect to the Enclave container and administer the network as required.
