- 67. Build • Static analysis via HHVM • Actually was implemented, but hphpa changed a lot (now it’s https://github.com/sebastianbergmann/hhvm- wrapper) Deployment • Cronjob / CLI script handling • Web server (Apache, nginx) config manipulations • Ext- and lib- dependency verification via Composer • Custom script execution during deployment What is not implemented yet 67
- 68. Questions?
Editor's Notes
- #5: Speech includes not only slides and copy-paste from manual, but also a real practice P.S. A lot of well-known demotivators and gags are included)
- #8: практика разработки программного обеспечения, которая заключается в выполнении частых автоматизированных сборок проекта для скорейшего выявления и решения интеграционных проблем
- #11: envs: dev/ci/qa/staging/uat/production
- #13: What to build? Install vendors Perform static analysis& validation Prepare assets Run tests Compress into archive
- #14: Ant: From Java world, XML declarative config, Can run tasks in parallel, No PHP-specific tasks, Could be extended (Java), IDE support Phing: Written in PHP, Ant config syntax, All tasks by default are running in the single PHP process, Could be extended (PHP), IDE support Pake: Written in PHP, Not so popular, PHP-based config Quiz: which tool is used by audience?
- #15: Target: Could depend on other targets, phing <taskname> Task: Custom tasks can be implemented, examples Types: Reference, FileSet, Property, FileList, Filters
- #23: list-updates = composer update –dry-run security-checker = security.sensiolabs.org
- #25: phpcs with custom configs for php & javascript
- #27: Regular: Copy config for CI server, warmup cache, install assets & dump them via Assetic DB-related: drop & re-create DB, run Doctrine Migrations, load fixtures, validate DB schema. dump schema to DDL file twig:lint for Bundles and app/Resources
- #28: Package: Add version to text file, add DDL schema schema.sql, package app, src, vendors, web to tar.gz Deployment (for specific Capifony subtasks: maintenance mode, backup DB, cleat Doctrine cache, cleanup old releases, deploy artifact)
- #30: Jenkins CI – ex-Hudson CI CruiseControl + PHP Under Control TeamCity, Bamboo: commercial Travis CI, Scrutinizer CI: SAAS Quiz: which tool is used by audience?
- #35: git: disable internal tagging! copyartifact: copy artifact from one job to another email-ext: sends emails on successful builds, useful for deployment jobs
- #36: phing checkstyle phpcs, hphpa dry phpcpd jdepend php_depend plot phploc using CSV files pmd phpmd violations aggregates info from phpcs, hphpa, phpmd, phpcpd xunit phpunit htmlpublisher HTML artifacts
- #37: build-<branchname>: Builds specific branch (master), Features are verified after merge build-package-tag: Parameterizedm Produces .tar.gz artifact from specific Git tag
- #38: deploy-qa-<branchname>: tar.gz from latest revision of branch, Deploys to QA, Not recommended to have more than one such job (issues with migrations), Workaround: multiple QA or complete DB purge on deploy deploy-package-tag: Deploys specific package from build-package-tag to specified environment, Ability to enable/disable maintenance mode and error message via parameters, Email after deployment
- #39: Previous deployed version examples: <tag>.<build#> = v0.0.3.26, <branchname>-<build#>-<revision>-SNAPSHOT = master-12-7c041a90366ce9d958760094c763d809ffbc629e-SNAPSHOT
- #42: Capistrano: from Ruby world Capifony: Based on Capistrano, Implemented in liip/symfony-rad-edition Custom: deb, rpm / VCS update / Rsync, FTP, SCP / Shell script Phar: Don’t use WebPhar, Silex does not use it anymore Zend Server package: No support for vanilla PHP, Zend Continuous Delivery Blueprint PaaS: AWS Elastic Beanstalk, PagodaBox Quiz: which tool is used by audience?
- #43: Capistrano: from Ruby world Capifony: Based on Capistrano, Implemented in liip/symfony-rad-edition Custom: deb, rpm / VCS update / Rsync, FTP, SCP / Shell script Phar: Don’t use WebPhar, Silex does not use it anymore Zend Server package: No support for vanilla PHP, Zend Continuous Delivery Blueprint PaaS: AWS Elastic Beanstalk, PagodaBox Quiz: which tool is used by audience?
- #44: Based on Capistrano: Supports Capistrano plugins
- #52: Sometimes there is no access to internet due to security limitations
- #53: Decreases deployment time: Lot of vendors, Slow internet connection
- #54: Reproducible: You know what you deploy, You can deploy exactly the same package to multiple environments Quick fixes (git commit + git pull) not available
- #58: pros / contras of maintenance mode 24x7 + users always have good UX (some functionality could be disabled / read only), ~99.999% uptime $$$ (implementation, testing, support & maintenance, hardware resources) complexity
- #59: User Triggers job on Jenkins CI, Choose options (env, maintenance mode) Jenkins Executes phing target with additional CLI arguments Phing Executes several Capifony commands according to command-line arguments Capifony Performs actions on remote machines
- #60: Maintenance mode maintenance.html in webroot Clear Doctrine cache Not for APC cache Downloads previous deploy metadata package version, Doctrine Migrations info
- #61: Restarts services: php-fpm or Apache, Doctrine APC cache is cleared Symfony-specific tasks: copy app/config/parameters.yml, doctrine:migrations:migrate, cache:warmup
- #62: Housekeeping: Perform cleanup for old releases
- #64: Semi-automatical: from deployment server, usually CI server Enable Maintenance: manually via phing Manually backup for analysis: DB, current version, Doctrine Migrations status, codebase
- #65: Switch to previous release: Manually via capifony CLI Recover DB: Rollback Doctrine Migrations, Restore DB dump, Custom Additional tasks: Restore web server config, Restart service, cache:warmup Disable Maintenance Manually via phing
- #66: Write rollback guide: Step-by-step, Verify it periodically Enable monitoring on prod: Zabbix, Pinba, Munin, New Relic, Graylog2
