Install Nomad
The task drivers that are available to Nomad vary by operating system,
for example Docker is only available on Linux machines. To simplify the
getting started experience, we will be working in a Vagrant environment.
Create a new directory, and download this Vagrantfile.
Vagrant Setup
Note: To use the Vagrant Setup first install Vagrant following these instructions: https://www.vagrantup.com/docs/installation/
Once you have created a new directory and downloaded the Vagrantfile
you must create the virtual machine:
$ vagrant up
This will take a few minutes as the base Ubuntu box must be downloaded and provisioned with both Docker and Nomad. Once this completes, you should see output similar to:
Bringing machine 'default' up with 'vmware_fusion' provider...
==> default: Checking if box 'puphpet/ubuntu1404-x64' is up to date...
==> default: Machine is already running.
At this point the Vagrant box is running and ready to go.
Verifying the Installation
After starting the Vagrant box, verify the installation worked by connecting
to the box using SSH and checking that nomad is available. By executing
nomad, you should see help output similar to the following:
$ vagrant ssh
...
vagrant@nomad:~$ nomad
usage: nomad [--version] [--help] <command> [<args>]
Available commands are:
agent Runs a Nomad agent
agent-info Display status information about the local agent
alloc-status Display allocation status information and metadata
client-config View or modify client configuration details
eval-status Display evaluation status and placement failure reasons
fs Inspect the contents of an allocation directory
init Create an example job file
inspect Inspect a submitted job
logs Streams the logs of a task.
node-drain Toggle drain mode on a given node
node-status Display status information about nodes
plan Dry-run a job update to determine its effects
run Run a new job or update an existing job
server-force-leave Force a server into the 'left' state
server-join Join server nodes together
server-members Display a list of known servers and their status
status Display status information about jobs
stop Stop a running job
validate Checks if a given job specification is valid
version Prints the Nomad version
If you get an error that Nomad could not be found, then your Vagrant box
may not have provisioned correctly. Check for any error messages that may have
been emitted during vagrant up. You can always destroy the box and
re-create it.
Next Steps
Vagrant is running and Nomad is installed. Let's start Nomad!
