Deploy your application in a box @willemjanz joind.in/talk/73636
Willem-Jan Zijderveld @willemjanz github.com/wjzijderveld
Don't wait till the last slide with questions
Deployment With the usual disclaimer
It works So why change it?
Can you deploy whenever you want?
Are you ever hesitant to deploy?
"We can't deploy, Robin is sick today"
Do users notice when you deploy?
Things break If you like it or not
Deployments fail • Network issues • Migrations • Broken configuration
Downtime
Missed revenue
Angry customers
Customers losing faith
Scared to deploy
Deployments get postponed
Reserving dedicated time to deploy
Deploying outside office hours...
So what would be a more optimal method?
Less humans
No sweat
More often
0 downtime
Repeatable
Let's get started
Less humans Automate your deploy process to a single step
Possible deployment Migrate database Update code on server (FTP, SSH)
Update code dependencies (composer,npm,bower) Clear cache Reload webserver
> ssh your-server.com > sudo su - > cd /var/www/
> git pull > php composer.phar install > npm install > rm -rf app/cache/* > # Some permission commands > service php-fpm reload Example: before
Example: after > ssh
[email protected]
> ./deploy.sh * Pulling changes
* Updating dependencies * Migrating database * Clearing cache * DEPLOYED NEW VERSION
No sweat Lose the fear of deploying
Testing
Seriously, test your code
New code should have tests
Legacy code? Test the critical parts - Unit tests for
important (domain) logic - Functional tests - Monitor production
Continuous Integration
More often
Smaller changes
6 month projects Deliver something every day Don't wait with
deploying until your feature is ready and approved.
Short lived branches • Allows for rapid deployment • Prevents
huge merge conflicts • Speeds up overall development
Feature toggles
Example: recommendations <?php // BasketController.php function actionBasket(User $user) { $basket
= $this->getBasketOfUser($user); $response = ['basket' => $basket->toArray()]; if ($this->featureIsActive('recommendations')) { $response['recommendations'] = $this->getRecommendations($basket); } return new JsonResponse($response); }
Example: recommendations <?php // BasketController.php function actionBasket(User $user) { $basket
= $this->getBasketOfUser($user); $response = ['basket' => $basket->toArray()]; if ($this->featureIsActive('recommendations')) { $response['recommendations'] = $this->getRecommendations($basket); } return new JsonResponse($response); }
Give some users access
Conditional toggle Check the context against the conditions of the
toggle
Example: Conditional toggle <?php $toggle = new Toggle( 'recommendations', ['user_id'
=> GreaterThan(42)] ); $toggle->active(['user_id' => 21]); // true $toggle->active(['user_id' => 1337]); // false
Example: Conditional toggle <?php $toggle = new Toggle( 'recommendations', ['user_id'
=> GreaterThan(42)] ); $toggle->active(['user_id' => 21]); // true $toggle->active(['user_id' => 1337]); // false
Example: Conditional toggle <?php $toggle = new Toggle( 'recommendations', ['user_id'
=> GreaterThan(42)] ); $toggle->active(['user_id' => 21]); // true $toggle->active(['user_id' => 1337]); // false
Example: Conditional toggle <?php $toggle = new Toggle( 'recommendations', ['user_id'
=> GreaterThan(42)] ); $toggle->active(['user_id' => 21]); // true $toggle->active(['user_id' => 1337]); // false
Feature management GUI API Redis http://labs.qandidate.com/blog/2014/08/19/open-sourcing-our-feature-toggle-api-and-ui/
More often - Smaller iterations - Don't wait for the
whole feature to complete - Make use of feature toggles
0 downtime

Example /var /project /releases /20160608-1.0 /20160609-1.1 /current -> /var/project/releases/20160608-1.0
0 downtime - Don't touch the current version - Abort
when any of the steps fail - Make your migrations backwards compatible
Put it in a box
Repeatable
Environment independent
The box In it's simplest form: just a zip
Independent
Reusable On all environments
Some challenges
Filesystem
<!-- services.xml --> <services> <service id="uploader" class="AppBundle\Uploader"> <argument>/var/www/uploads/</argument> </service> </services>
Flysystem Abstract the filesystem - Makes it easier to test
- Makes your code independent of the filesystem, f.e.: - Production uses S3 - Development uses local files
<!-- services.xml --> <services> <service id="uploader" class="AppBundle\Uploader"> <argument type="service" id="oneup_flysystem.private_filesystem"
/> </service> </services>
# config.yml oneup_flysystem: adapters: private_s3: awss3v2: client: aws_s3_client bucket: %s3_private_files_bucket%
filesystem: private: adapter: private_s3
<?php // Uploader.php function uploadAvatar($filename) { $stream = fopen($filename, 'r+');
$this->filesystem ->writeStream('avatars/' . $filename, $stream); if (is_resource($stream)) { fclose($stream); } }
File is now at S3: bucket/avatars/filename. ext
Configuration
# config_prod.yml imports: - { resource: config.yml } doctrine: dbal:
default_connection: default connections: default: driver: pdo_mysql host: 192.168.1.10 dbname: acme_prod user: acme_prod password: SuperSecure
What about staging and acceptance?
Give control to the environment
# config.yml imports: - { resource: parameters.yml } - {
resource: parameters.php } doctrine: dbal: default_connection: default connections: default: driver: pdo_mysql host: %db.hostname% dbname: %db.name% user: %db.user% password: %db.password%
# config.yml imports: - { resource: parameters.yml } - {
resource: parameters.php } doctrine: dbal: default_connection: default connections: default: driver: pdo_mysql host: %db.hostname% dbname: %db.name% user: %db.user% password: %db.password%
# config.yml imports: - { resource: parameters.yml } - {
resource: parameters.php } doctrine: dbal: default_connection: default connections: default: driver: pdo_mysql host: %db.hostname% dbname: %db.name% user: %db.user% password: %db.password%
<?php // parameters.php $parameterMapping = [ 's3_private_files_bucket' => 'MYAPP_S3_PRIVATE_FILES_BUCKET', ];
foreach ($parameterMapping as $parameter => $env) { if (false !== ($value = getenv($env))) { $container->setParameter($parameter, $value); } }
$_ENV['SYMFONY__*'] But those values get overwritten by parameters defined in
config.yml / parameters.yml
PHP dot env https://github.com/vlucas/phpdotenv
<?php // web/index.php $dotenv = new Dotenv\Dotenv(__DIR__ . '/../'); $dotenv->load();
Load .env # .env MYAPP_S3_PRIVATE_FILES_BUCKET=yourbucket
Building the box - Should be reusable - Eliminate hard
dependencies on environment - Give control to the environment
Summary - Less manual steps, eliminate the humans - Lose
the fear: test your stuff - Deploy more often, don't postpone - Deployment shouldn't cause downtime - A deployment should be repeatable
