The EngineYard gem (EY) is no longer maintained. Please switch to ey-core which can be found on rubygems.org and the repo can be found here
ey engineyard Command Line Interface
The Engine Yard command line utility.
Installing on Ruby 1.8.7 or 1.9.2
NOTE: This has no effect on your Engine Yard environment ruby version. This is only regarding the local development Ruby version for running this gem. An environment can continue using a chosen Ruby version regardless of this change.
This gem now wraps the ey-core gem by default.
If you wish to access the old gem behavior, call the binary as ey legacy and then append
the rest of the command as normal. This legacy behavior will be phased out over time.
Install
Install engineyard like any other ruby gem:
gem install engineyard
Note: Don't add engineyard to your application's Gemfile. The engineyard gem is not made to be a part of your application and may cause version conflicts with other parts of rails.
Login
The first command you run will notice that you are not logged in and will ask you for your Engine Yard email and password.
Configuration
The ey.yml file allows options to be saved for each environment to which an
application is deployed.
A typical Rails application will have a config/ey.yml like this:
---
# This is all you need for a typical rails application.
defaults:
migrate: true
migration_command: rake db:migrate
precompile_assets: true
The following ey.yml file shows other things that can be customized.
A typical application will not need most of these options.
---
# 'defaults' applies to all environments running this application.
# Only set these options if needed. The defaults are correct for most applications.
defaults:
bundler: detect # By default, bundler is detected via Gemfile. Options: true: always run bundler; false: never run bundler
composer: detect # By default, composer is detected via composer.lock. Options: true: always run composer; false: never run composer
npm: detect # By default, npm is detected via package.json. Options: true: always run npm; false: never run npm
bundle_without: GROUP1 GROUP2 # exclude groups on bundle install (default: test development)
bundle_options: --OPTION # extra bundle install options (--local, --quiet, etc; does not override bundle_without)
copy_exclude: # don't rsync the following dirs (some people like to skip .git)
- SOME_LARGE_DIR
keep_releases: 3 # number of releases to keep in /data/APP_NAME/releases. Older releases are removed. Default: 3
maintenance_on_restart: false # show maintenance page during app restart (default: false except for glassfish and mongrel)
maintenance_on_migrate: true # show maintenance page during migrations (default: true)
precompile_assets: true # enables rails assets precompilation (default: inferred using app/assets and config/application.rb)
precomplie_assets_task: assets:precompile # override the assets:precompile rake task
precompile_unchanged_assets: false # if true, does not check git for changes before precompiling assets.
asset_dependencies: # a list of relative paths to search for asset changes during each deploy.
- app/assets # default
- lib/assets # default
- vendor/assets # default
- Gemfile.lock # default
- config/routes.rb # default
- config/application.rb # default
- config/requirejs.yml # custom option (be sure to include defaults if you specify this option)
asset_strategy: shifting # choose an alternet asset management strategy. See rails_assets/strategy.rb for more info.
asset_roles: :all # specify on which roles to compile assets (default: [:app, :app_master, :solo])
ignore_database_adapter_warning: true # hide database adapter warning if you don't use MySQL or PostgreSQL (default: false)
# Environment specific options apply only to a single environment and override settings in defaults.
environments:
env_production:
precompile_unchanged_assets: true # precompiles assets even if no changes would be detected (does not check for changes at all).
asset_strategy: shifting # choose an alternet asset management strategy (shifting, cleaning, private, shared)
asset_roles: :all # specify on which roles to compile assets (default: [:app, :app_master, :solo] - must be an Array)
env_staging
asset_strategy: private # Use an asset management that always refreshes, so staging enviroments don't get conflicts
These options in ey.yml will only work if the file is committed to your
application repository. Make sure to commit this file. Different branches
may also have different versions of this file if necessary. The ey.yml file
found in the deploying commit will be used for the current deploy.
Commands
ey init
Initialize a repository for deployment on Engine Yard Cloud.
This command writes or updates an ey.yml file which explains options available for customizing the deployment process.
ey init can be run in existing applications to update the ey.yml file
without losing existing settings.
NOTE: Please verify all settings and changes after running ey init for the first time.
ey deploy
This command must be run within the current directory containing the app to be
deployed. If ey.yml specifies a default branch then the ref parameter can be
omitted. Furthermore, if a default branch is specified but a different
command is supplied the deploy will fail unless --ignore-default-branch
is used.
If ey.yml does not specify a default migrate choice, you will be prompted to
specify a migration choice. A different command can later be specified via
--migrate "ruby do_migrations.rb". Migrations can also be skipped entirely
by using --no-migrate.
Options:
-r, [--ref=REF] [--branch=] [--tag=] # Git ref to deploy. May be a branch, a tag, or a SHA.
-c, [--account=ACCOUNT] # Name of the account in which the environment can be found
-a, [--app=APP] # Name of the application to deploy
-e, [--environment=ENVIRONMENT] # Environment in which to deploy this application
-m, [--migrate=MIGRATE] # Run migrations via [MIGRATE]; use --no-migrate to avoid running migrations
-v, [--verbose] # Be verbose
[--ignore-default-branch] # Force a deploy of the specified branch even if a default is set
[--ignore-bad-master] # Force a deploy even if the master is in a bad state
[--extra-deploy-hook-options key:val] # Additional options to be made available in deploy hooks (in the 'config' hash)
# Add more keys as follows: --extra-deploy-hook-options key1:val1 key2:val2
ey timeout-deploy
The latest running deployment will be marked as failed, allowing a new deployment to be run. It is possible to mark a potentially successful deployment as failed. Only run this when a deployment is known to be wrongly unfinished/stuck and when further deployments are blocked.
NOTICE: This command is will indiscriminately timeout any deploy, with no regard for its potential success or failure. Confirm that the running deploy is actually stuck or broken before running this command. If run against a deploy that would succeed, it could cause the deployment to be marked as failed incorrectly.
Options:
-c, [--account=ACCOUNT] # Name of the account in which the environment can be found
-a, [--app=APP] # Name of the application containing the environment
-e, [--environment=ENVIRONMENT] # Name of the environment with the desired deployment
ey status
Show the status of most recent deployment of the specified application and environment. This action only informational and will not change your application.
Options:
-c, [--account=ACCOUNT] # Name of the account in which the environment can be found
-a, [--app=APP] # Name of the application containing the environment
-e, [--environment=ENVIRONMENT] # Name of the environment with the desired deployment
ey environments
By default, environments for this app are displayed. The --all option will
display all environments, including those for this app.
Options:
-c, [--account=ACCOUNT] # Name of the account in which the environment can be found
-a, [--app=APP] # Name of the application containing the environments
-e, [--environment=ENVIRONMENT] # Show only environments matching named environment
-s, [--simple] # Print each environment name on its own on a new line
-a, [--all] # Show all environments, not just ones associated with this application.
ey servers
List all servers on an environment.
Options:
-c, [--account=ACCOUNT] # Name of the account in which the environment can be found
-e, [--environment=ENVIRONMENT] # Show only servers in the named environment
-u, [--user] # Print the user@ in front of the server hostname to make ssh connections simpler
-s, [--simple] # Print each server on a new line with hostname, role, and name separated by tabs
-S, [--host] # Print each server on a new line with hostname only. Use -Su for 'user@host'
Example output:
$ ey servers -s
ec2-10-0-0-0.us-west-2.compute.amazonaws.com i-aabbccdd app_master
ec2-10-0-0-1.us-west-2.compute.amazonaws.com i-bbccddee app

Options:
-e, [--environment=ENVIRONMENT] # Environment with the interesting logs
-c, [--account=ACCOUNT] # Name of the account in which the environment can be found
ey rebuild
Engine Yard's main configuration run occurs on all servers. Mainly used to fix failed configuration of new or existing servers, or to update servers to latest Engine Yard stack (e.g. to apply an Engine Yard supplied security patch).
Note that uploaded recipes are also run after the main configuration run has successfully completed.
This command will return immediately, but the rebuild process may take a few minutes to complete.
Options:
-e, [--environment=ENVIRONMENT] # Environment to rebuild
-c, [--account=ACCOUNT] # Name of the account in which the environment can be found
ey rollback
Uses code from previous deploy in the /data/APP_NAME/releases directory on
remote server(s) to restart application servers.
Options:
-v, [--verbose] # Be verbose
-a, [--app=APP] # Name of the application to roll back
-e, [--environment=ENVIRONMENT] # Environment in which to roll back the application
-c, [--account=ACCOUNT] # Name of the account in which the environment can be found
ey recipes apply
This is similar to ey rebuild except Engine Yard's main configuration step is
skipped.
Options:
-e, [--environment=ENVIRONMENT] # Environment in which to apply recipes
-c, [--account=ACCOUNT] # Name of the account in which the environment can be found
ey recipes upload
The current directory should contain a subdirectory named cookbooks to be
uploaded.
Options:
-e, [--environment=ENVIRONMENT] # Environment that will receive the recipes
-c, [--account=ACCOUNT] # Name of the account in which the environment can be found
[--apply] # Apply the recipes (same as above) immediately after uploading
-f, [--file=FILE] # Specify a gzipped tar file (.tgz) for upload instead of cookbooks/ directory
ey recipes download
The recipes will be unpacked into a directory called cookbooks in the current
directory. If the cookbooks directory already exists, an error will be raised.
Options:
-e, [--environment=ENVIRONMENT] # Environment for which to download the recipes
-c, [--account=ACCOUNT] # Name of the account in which the environment can be found
ey web enable
Remove the maintenance page for this application in the given environment.
Options:
-v, [--verbose] # Be verbose
-a, [--app=APP] # Name of the application whose maintenance page will be removed
-e, [--environment=ENVIRONMENT] # Environment on which to take down the maintenance page
-c, [--account=ACCOUNT] # Name of the account in which the environment can be found
ey web disable
The maintenance page is taken from the app currently being deployed. This means that you can customize maintenance pages to tell users the reason for downtime on every particular deploy.
Maintenance pages searched for in order of decreasing priority:
- public/maintenance.html.custom
- public/maintenance.html.tmp
- public/maintenance.html
- public/system/maintenance.html.default
Options:
-v, [--verbose] # Be verbose
-a, [--app=APP] # Name of the application whose maintenance page will be put up
-e, [--environment=ENVIRONMENT] # Environment on which to put up the maintenance page
-c, [--account=ACCOUNT] # Name of the account in which the environment can be found
ey web restart
Restarts the application servers for the given application. Enables maintenance
pages if it would be enabled during a normal deploy. Respects the
maintenance_on_restart ey.yml configuration.
Options:
-v, [--verbose] # Be verbose
-a, [--app=APP] # Name of the application to restart
-e, [--environment=ENVIRONMENT] # Name of the environment to restart
-c, [--account=ACCOUNT] # Name of the account in which the app and environment can be found
ey ssh
If a command is supplied, it will be run, otherwise a session will be opened.
The application master is used for environments with clusters. Option --all
requires a command to be supplied and runs it on all servers.
Note: this command is a bit picky about its ordering. To run a command with
arguments on all servers, like rm -f /some/file, you need to order it like so:
$ ey ssh "rm -f /some/file" -e my-environment --all
Options:
[--utilities=one two three] # Run command on the utility servers with the given names. If no names are given, run on all utility servers.
[--app-servers] # Run command on all application servers
[--db-servers] # Run command on the database servers
[--db-master] # Run command on the master database server
-A, [--all] # Run command on all servers
[--db-slaves] # Run command on the slave database servers
-e, [--environment=ENVIRONMENT] # Name of the environment to ssh into
-c, [--account=ACCOUNT] # Name of the account in which the environment can be found
-s, [--shell] # Use a particular shell instead of the default bash
[--no-shell] # Don't use a shell to run the command (default behavior of ssh)
ey launch
Open the application in a browser.
Options:
-c, [--account=ACCOUNT] # Name of the account in which the environment can be found
-a, [--app=APP] # Name of the application to launch
-e, [--environment=ENVIRONMENT] # Name of the environment for the application
ey whoami
Who am I logged in as? Prints the name and email of the current logged in user.
ey login
Log in and verify access to EY Cloud. Use logout first if you need to switch user accounts.
ey logout
Remove the current API key from ~/.eyrc or file at env variable $EYRC
Global Options
All commands accept the following options.
--api-token=API_TOKEN # Use API-TOKEN to authenticate this command
--serverside-version=SERVERSIDE_VERSION # Please use with care! Override deploy system version
# (same as ENV variable ENGINEYARD_SERVERSIDE_VERSION)
Not all commands will make use of these options. For example, ey status does not use, and will ignore the --serverside-version flag.
Also, please consider that it's usually not a good idea to override the version of serverside unless you know what you're doing. CLI and serverside versions are designed to work together and mixing them can cause errors.
API Client
See engineyard-cloud-client for the API client library.
DEBUG
The API commands will print internal information if $DEBUG is set:
$ DEBUG=1 ey environments --all
GET https://cloud.engineyard.com/api/v2/apps
Params {"no_instances"=>"true"}
Headers {"User-Agent"=>"EngineYard/2.0.0 EngineYardCloudClient/1.0.5",
"Accept"=>"application/json",
"X-EY-Cloud-Token"=>"YOURTOKEN"}
Response {"apps"=>
[{"environments"=>[],
"name"=>"myapp",
"repository_uri"=>"git@github.com:myaccount/myapp.git",
"app_type_id"=>"rails3",
"account"=>{"name"=>"myaccount", "id"=>1234},
"id"=>12345}]}
Releasing
To release the engineyard gem, use the command below and then follow the instructions it outputs.
bundle exec rake release
This will remove the .pre from the current version, then bump the patch level
and add .pre after for the next version. The version will be tagged in git.
To release a new engineyard-serverside gem that has already been pushed to
rubygems.org, update lib/engineyard/version.rb to refer to the
engineyard-serverside version you want to release, then make a commit.
Each engineyard gem is hard-linked to a specific default engineyard-serverside
version which can be overriden with the --serverside-version option.
The engineyard-serverside-adapter version does not need to be bumped in the
gemspec unless you're also releasing a new version of that gem. Versions
of adapter are no longer linked to serverside.
