Spearhead Docker CLI helper

This script will install compatible Docker versions for use with the Spearhead Cloud.

Your existing Docker will not be affected and you can conveniently switch between your own Docker and the Spearhead Cloud docker tools.

Compatibility and requirements

This is designed and tested for Linux and MacOS X.

This code requires Spearhead Cloud CLI tool and a Spearhead Cloud account.

Installation

In a terminal window, run the following command:

sudo bash -c 'curl -o /usr/local/bin/spearhead-docker https://code.spearhead.cloud/Spearhead/spearhead-docker-cli/raw/branch/master/spearhead-docker && chmod +x /usr/local/bin/spearhead-docker && ln -Fs /usr/local/bin/spearhead-docker /usr/local/bin/spearhead-compose && ln -Fs /usr/local/bin/spearhead-docker /usr/local/bin/spearheadn-docker-install'

That command will copy the spearhead-docker shell script from this repo, and link it as spearhead-compose and spearhead-docker-install.

To complete the installation, run sudo spearhead-docker-install to install the platform-specific versions of the Docker (now Moby) and Docker Compose CLI tools. These versions will not replace any existing Docker or Docker Compose versions you may have installed.

Usage

Once installed, use spearhead-docker and spearhead-compose in place of docker and docker-compose when interacting with the Spearhead Cloud.

Start a Docker container running Nginx container on Spearhead Cloud:

$ spearhead-docker run -d -p 80 --name webserver nginx
Executing in 'ro-1' (default; use `spearhead profile set <profile name>` to change) at 05:02:41 AM

$

Start all the containers to run WordPress via Docker Compose on Spearhead Cloud:

$ spearhead-compose up -d
Executing in 'ro-1' (default; use `spearhead profile set <profile name>` to change) at 03:15:56 PM

This will also set some helpful environment variables for using Triton Container Name Service (CNS):

SC_CNS_SEARCH_DOMAIN_PUBLIC
SC_CNS_SEARCH_DOMAIN_PRIVATE

Those vars will be automatically set with values appropriate for use in Spearhead Public Cloud:

SC_CNS_SEARCH_DOMAIN_PRIVATE=a42e7881-89d2-459e-bc0b-e9af0bca409a.us-east-3.cns.spearhead.cloud
SC_CNS_SEARCH_DOMAIN_PUBLIC=a42e7881-89d2-459e-bc0b-e9af0bca409a.us-east-3.spearhead.cloud
