build_nomad.sh

#!/bin/sh

# here is a helper script which sets up the go dependencies for nomad, 
# builds the project executable, and packages that up in a zip file for
# distribution through your own channels. This zip can be push to S3,
# hosted on CM (salt), etc

# modify $VERSION, though that's just a surface detail

# run as root or with sudo
#apt-get update

release-checksum.md

To download and generate checksums for bunch of releases at once

docker-compose

First, set the VERSIONS:

VERSIONS="1.7.1 1.7.0 1.6.2 1.6.1 1.6.0 1.5.2"

Then wget and sha512sum those in a loop:

for v in $VERSIONS
  do
  wget -o download.log -O docker-compose-Linux-x86_64-$v https://github.com/docker/compose/releases/download/$v/docker-compose-Linux-x86_64
  sha512sum docker-compose-Linux-x86_64-$v
done

Output looks like:

Hashicorp Tools

Set the app, and versions to target:

APP=vault
VERSIONS="0.5.1 0.5.2 0.5.3 0.6.0"

Then wget and sha512sum those in a loop:

for v in $VERSIONS
  do
  wget -o download.log -O ${APP}_${v}_linux_amd64.zip https://releases.hashicorp.com/$APP/$v/${APP}_${v}_linux_amd64.zip
  sha512sum ${APP}_${v}_linux_amd64.zip
