st2vagrant

Setup StackStorm (st2) on your laptop with Vagrant and VirtualBox, so you can play with it locally and develop integration and automation packs.

If you are fluent with Vagrant, you know where to look and what to do. If you are new to Vagrant, just follow along with step-by-step instructions below.

Pre-requisites

Simple installation

Clone the st2vagrant repo, and start up Vagrant:

git clone https://github.com/StackStorm/st2vagrant.git
cd st2vagrant
vagrant up

This command will download a vagrant box, create a virtual machine, and start a script to provision the most recent unstable version of StackStorm. You will see a lot of text, some of that may be red, but not to worry, it's normal. After a while, you should see a large ST2 OK, which means that installation successful and a VM with StackStorm is ready to play. Log in to VM, and fire some st2 commands:

vagrant ssh
st2 --version
st2 action list

The WebUI is available at https://192.168.56.20. The default st2admin user credentials are in Vagrantfile, usually st2admin:Ch@ngeMe.

You are in business! Go to QuickStart and follow along.

To configure ChatOps, review and edit /opt/stackstorm/chatops/st2chatops.env configuration file to point to Chat Service you are using. See details in "Setup ChatOps" section in installation docs for your OS (e.g, here is one for Ubuntu).

The Brocade Workflow Composer bits are not yet installed; to add them and get Workflow Designer, RBAC, and LDAP, follow these instructions to obtain a license key and install BWC.

If something went wrong, jump to Troubleshooting section below.

Customize your st2 installation

Environment variables can be used to enable or disable certain features of the StackStorm installation:

  • RELEASE - stable for the latest stable release, or unstable for a current version from dev trunk. DEFAULT: unstable
  • VAGRANT_HOSTNAME - the hostname to give the VM. DEFAULT: st2vagrant
  • BOX - the Vagrant base box to use. DEFAULT: ubuntu/bionic64
  • ST2USER - Username for st2. DEFAULT: st2admin
  • ST2PASSWORD - Password for st2. DEFAULT: Ch@ngeMe
  • VERSION - the version of StackStorm to install: 3.2

Set the variables by pre-pending them to vagrant up command. In the example below, it will install a version of st2 from development trunc, and set password to secret:

RELEASE="unstable" ST2PASSWORD="secret" vagrant up

To evaluate StackStorm on supported OS flavors, consider using the boxes we use for testing st2 for best results:

  • ubuntu/focal64 for Ubuntu 20.04
  • ubuntu/bionic64 for Ubuntu 18.04 (default)
  • ubuntu/xenial64 for Ubuntu 16.04
  • ubuntu/trusty64 for Ubuntu 14.04
  • bento/centos-6.7 for CentOS 6.7
  • centos/7 for CentOS 7
  • rockylinux/8 for RockyLinux 8

Examples:

BOX="centos/7" vagrant up
BOX=centos/7 RELEASE=stable vagrant up

Or use your favorite vagrant box. Note that StackStorm installs from native Linux packages, which are built for following OSes only. Make make sure the OS flavor of your box is one of the following:

  • Ubuntu 20.04 (Focal Fossa)

  • Ubuntu 18.04 (Bionic Beaver) (default)

  • Ubuntu 16.04 (Xenial Xerus)

  • Ubuntu 14.04 (Trusty Tahr)

  • CentOS 7 / RHEL 7

  • RockyLinux 8 / RHEL 8

Synced folders

Warning:

If you mount the above synced folder prior to ST2 installation, the installation may fail due to synced folders not supporting ownership and/or permissions changes by default. Also, notice that if you enable the above synced folder, it will hide the vagrant box's local /opt/stackstorm/packs folder. You will need to move the core packages here for ST2 to run properly.

By the time you read this hint, your VM is most likely already up and running. Not to worry: just uncomment the above mentioned line in your Vagrantfile and run vagrant reload --no-provision. This will restart the VM and apply the new config without running the provision part, so you won't reinstall st2. Vagrant will however ask you for your laptop password to sync the folders.

For details on NFS refer: https://www.vagrantup.com/docs/synced-folders/nfs.html

To learn about packs and how to work with them, see StackStorm documentation on packs!

Using the vmware_desktop provider

If you wish to startup a VM with the VMWare Workstation or VMWare Fusionproviders, eg: vmware_desktop , you will need to specify SYNCED_FOLDER_OPTIONS=vmware when running vagrant up.

SYNCED_FOLDER_OPTIONS=vmware BOX=bento/centos-7.6 RELEASE=stable vagrant up

If you have multiple providers installed, to force the vmwware_desktop provider:

VAGRANT_DEFAULT_PROVIDER=vmware_desktop SYNCED_FOLDER_OPTIONS=vmware BOX=bento/centos-7.6 RELEASE=stable vagrant up

Only the bento/centos-7.6 has been tested. This vagrant box reliably ships with VMWare tools installed for synced folders.

The options to synced_folder are the following for the VM provider:

Provider Synced folder options
VMWare **{} (no options)
Virtualbox (default) **{nfs: true, mount_options: ["nfsvers=3"]}

Using the libvirt provider (KVM)

If you want to run the the VM with KVM/libvirt simply do:

BOX=generic/ubuntu1804 vagrant up --provider libvirt
BOX=centos/7 vagrant up --provider libvirt
BOX=rockylinux/8 vagrant up --provider libvirt

Common synced folders for Pack development

Playing with StackStorm ranges from creating rules and workflows, to turning your scripts into actions, to writing custom sensors. And all of that involves working with files under /opt/stackstorm/packs on st2vagrant VM. One can do it via SSH, but with all your favorite tools already set up on your laptop, it's convenient to hack files and work with git there on the host.

You can create your pack directories under st2vagrant/ on your host. Vagrant automatically maps it's host directory to /vagrant directory on the VM, where you can symlink files and dirs to desired locations.

Alternatively, you can specify a comma-separated list of common synced folders in the the SYNCED_FOLDERS environment variable to mount them in the guest VM.

SYNCED_FOLDERS=packs,datastore_load vagrant up

Available common synced folders are:

Host folder Guest folder
. /vagrant
./config /opt/stackstorm/config
./packs /opt/stackstorm/packs
./packs_dev /opt/stackstorm/packs_dev
./datastore_load /opt/stackstorm/datastore_load

Custom synced folders

If you would like to use synced folders that are not one of the common synced folders, you can specify a comma-separated list of custom folders to sync in the CUSTOM_SYNCED_FOLDERS environment variable.

There are different ways to specify synced folders. You can specify just the host folder, which will be mounted to /home/vagrant/{folder} within the guest, using the mount settings specified with SYNCED_FOLDER_OPTIONS.

CUSTOM_SYNCED_FOLDERS=../st2client.js,../hubot-stackstorm vagrant up

will mean ../st2client.js and ../hubot-stackstorm will be mounted into /home/vagrant/st2client.js and /home/vagrant/hubot-stackstorm, respectively, in the guest.

You can also specify the host folder as well as the guest folder, by separating them with a ::

CUSTOM_SYNCED_FOLDERS=../st2client.js:/custom/dir/st2client.js,../hubot-stackstorm:/custom/dir/hubot-stackstorm vagrant up

This will mount the directories into /custom/dir/st2client.js and /custom/dir/hubot-stackstorm, respectively, using the default mount settings specified with SYNCED_FOLDER_OPTIONS.

Finally, you can specify mount options individually for each synced folder by adding them after another ::

CUSTOM_SYNCED_FOLDERS=../st2client.js:/custom/dir/st2client.js:{disabled:true},../hubot-stackstorm:/custom/dir/hubot-stackstorm:{custom_option:["nfsvers=3"]} vagrant up

The options will be eval()ed (as a Ruby snippet) within the Vagrantfile, then used in a double splat argument. This means that you can specify all options to the vm.synced_folder function in these options.

Advanced Pack Development Synced Folder Workflow Strategy

One of the common use cases is pack development. In order to streamline a persistent local development environment, the following approach could be used:

Warning

Syncing the config directory before ST2 install will cause the installation to fail due to permissions. There is probably a workaround -> if you know it open an issue and let us know.

  1. Synced folders you may wish to utilize to speed up setup of Vagrant box:

    • config --> synced to /opt/stackstorm/config
    • datastore_load --> synced to /opt/stackstorm/datastore_load
    • packs_dev --> synced to /opt/stackstorm/packs_dev

  2. Folder usage:

    • config folder: You can persist pack configs such as aws.yaml or jira.yaml in this folder and they will be present after vagrant up
    • datastore_load: Use this folder to store a json file that you would import to the datastore using st2 key load /opt/stackstorm/datastore_load/mykeystoredata.json
    • packs_dev: Use this folder to iterate on packs you are developing. After you commit your changes you can install the pack in your Vagrant box:
      • cd /opt/stackstorm/packs_dev/YOUR_PACK_DIRECTORY
      • st2 pack install file:///$PWD [--python3]

  3. Additional information

    • This repo includes .gitignore entries for the 3 directories described above.
    • This approach remove any installation conflicts, and prevents confusion of installing dev packs into ST2, since the st2 pack install command will create a clone of the pack in /opt/stackstorm/packs directory.

See the NFS Advanced Pack Dev Approach and VMWARE HGFS Advanced Pack Dev Approach in the Vagrantfile for synced folder configs that follow this strategy.

Manual installation

To master StackStorm and understand how things are wired together, we strongly encourage you to [eventually] install StackStorm manually, following installation instructions. You can still benefit from this Vagrantfile to get the Linux VM up and running: follow instructions to install Vagrant & VirtualBox to get a Linux VM, and simply comment out the st2.vm.provision "shell"... section in your Vagrantfile before running vagrant up.

Common problems and solutions

IP Conflicts

In the event you receive an error related to IP conflict, Edit the private_neworks address in Vagrantfile, and adjust the third octet to a non-conflicting value. For example:

    # Configure a private network
    st2.vm.network :private_network, ip: "192.168.56.20"

Mounts

Sometimes after editing or adding NFS mounts via config.vm.synced_folder,and firing vagrant up or vagrant reload, you may see this:

==> st2express: Exporting NFS shared folders...
NFS is reporting that your exports file is invalid. Vagrant does
this check before making any changes to the file. Please correct
the issues below and execute "vagrant reload":

exports:3: path contains non-directory or non-existent components: /Volumes/Repo/st2
exports:3: path contains non-directory or non-existent components: /Volumes/Repo/st2contrib
exports:3: path contains non-directory or non-existent components: /Volumes/Repo/st2incubator
exports:3: no usable directories in export entry
exports:3: using fallback (marked offline): /Volumes/Repo

FIX: Remove residuals from /etc/exports file on the host machine, and do vagrant reload again.

Using st2vagrant for release testing

Creates a box from a specific development version of code:

BOX=centos/7 RELEASE=unstable VERSION=3.1dev vagrant up
