cd ~/appflow ; make install ; source ~/.zshrc
appflow local

Local development

appflow vagrant reload atlantis ; ssh atlantis

Remote provisioning

appflow provision env=production limit=webservers tenant=mrrobot tags=base_packages

Features

Provisioning:

  • Multitenant architecture (different teams with different environments)
  • Supports development, testing, staging and production
  • All configuration files are encrypted in git with ansible-vault
  • Provision all nodes with one command

Development:

  • Provides a Vagrant based development environment called atlantis
  • Code locally on any Unix-like system or Windows (cygwin)

Deployment:

Infrastructure:

Deployment requirements

Capistrano

Ubuntu

sudo apt-get install software-properties-common
sudo apt-add-repository ppa:brightbox/ruby-ng
sudo apt-get update
sudo apt-get install ruby2.3 libxml2-dev zlib1g-dev
sudo gem2.3 install bundler

Installation

  1. Create new config directory layout - mkdir -p ~/.appflow/{tenant,vault}
  2. Copy config.example to ~/.appflow/config and update variables:
    • CFG_TENANT_ID - identity of the own tenant
    • CFG_TENANT_NAME - name of the own tenant
    • CFG_TENANT_ENV - default provisioning environment
    • CFG_APPFLOW_SUPPORT_MAIL - e-mail address to send support requests to
  3. Copy the appflow-mrrobot folder in examples to ~/.appflow/tenant/
  4. Link the folder: ln -s ~/.appflow/tenant/appflow-mrrobot ~/.appflow/tenant/mrrobot
  5. Copy the vault folder in examples to ~/.appflow/vault

Now you are ready to deploy!
In the main appflow folder (where you cloned the repo) you can start provisioning with:
appflow provision env=development tenant=mrrobot

Documentation

Take a look at the walkthrough for initial setup.

For easy code management, just use:

appflow checkout env=production tenant=mrrobot
appflow decrypt env=production tenant=mrrobot
edit tenant's configs in ~/.appflow/tenant/appflow-mrrobot/production
appflow status env=production tenant=mrrobot
appflow checkin env=production tenant=mrrobot

Forgot what you've done? go back:

appflow reset env=production tenant=mrrobot

Want to update everything and provision?

appflow update ; appflow checkout ; appflow provision local=true

vagrant vbguest --status

Before you can appflow vm reload atlantis. This will download the needed trusty64 box.

appflow vagrant

Troubleshooting

[vagrant] Missing Vagrantfile.local.yml

Issue: There was an error loading a Vagrantfile. The file being loaded
       and the error message are shown below. This is usually caused by
       a syntax error.

       Path: /Users/foo/Documents/webdev/appflow/Vagrantfile
       Line number: 0
       Message: Errno::ENOENT: No such file or directory @ rb_sysopen - Vagrantfile.local.yml`

Solve: add Vagrantfile.local.yml to the appflow folder with this content:

       synced_folder:
         appflow_folder: "~/Documents/webdev/appflow"
         webdev_folder: "~/Documents/webdev/development"

[vagrant] Vagrant was unable to mount VirtualBox shared folders

Issue: Vagrant was unable to mount VirtualBox shared folders.
       This is usually because the filesystem "vboxsf" is not available.
       This filesystem is made available via the VirtualBox Guest Additions
       and kernel module. Please verify that these guest additions are properly
       installed in the guest. This is not a bug in Vagrant and is usually
       caused by a faulty Vagrant box. For context, the command attempted was:

       id -u deploy

       The error output from the command was:

       id: deploy: no such user

Solve: appflow provision limit=atlantis firstrun=true (password is vagrant).

[vagrant] The box you attempted to add doesn't match the provider you specified

Issue: The box you attempted to add doesn't match the provider you specified.

Solve: vagrant up --provider=virtualbox atlantis

[vagrant] Lost Vagrant reference to VirtualBox VM

Issue: Lost Vagrant reference to VirtualBox VM

Solve:
VBoxManage list vms
  "vagrant-atlantis" {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx}
echo xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx > ~/appflow/.vagrant/machines/atlantis/virtualbox/id
