Was werde ich jetzt erzählen

Definition Deployment
Einfaches Deployment
Automatisches Deployment
Deployment Workflows
Deployment Arichtekturen

Deployment = Verteilen

Etwas verteilen, Dinge gleicher oder ähnlicher Art an mehrere Ziele austeilen.

Wie wir Dinge verteilen?

Drag & Drop uploads

Drop your stuff here!

Manuelle uploads

FTP & Co.

Local	Remote
drwxr-xr-x . drwxr-xr-x .. drwxr-xr-x index.html	drag your file here!

Via Commandline (CLI)

SFTP - Secure File Transfer Protocol

sftp -P 42022 ~/development/db_dump rene.reimann@10.111.26.61:/home/dev_db_sync/db_dump/cts_seo.sql

SCP - Secure Copy

scp -P 42022 ~/development/db_dump rene.reimann@10.111.26.61:/home/dev_db_sync/db_dump/cts_seo.sql

Deployment like a Pro

Deployment Möglichkeiten

easy

semieasy

fullstack

Deployment easy

FTP-Programme mit Sync-Function: Transmit (mac)

Commandline Tools: rsync

$ rsync -a -e ssh root@192.168.0.100:/folder1/ /folder2/

Vorteile

Sehr einfach in der Hanhabung
Keine tiefergehendes Wissen nötig.

Nachteile

Wenig Kontrolle
Rollback kompliziert
Fehlerquote hoch

Deployment semieasy

Vorbereitung: mit Composer Projekte bauen

Vorteile

Volle Kontrolle über Änderungen
Entwickler haben gleiche Versionen
Code kann verisoniert werden
Composer kann Builds & Tests ausführen

Nachteile

Login auf dem Ziel Server nötig
Kein Rollback

Deployment full Stack

Mit Deployment Tools

Remote
Bessere Rechteverwaltung
Deploys werden Versioniert
Rollback
Continuous Integration
Staging

Deploy auf einen Teststage

$ dep deploy test

Deploy auf einen Production

$ dep deploy production

Wie Funktioniert das?

Die deployer.php


namespace Deployer;
require 'recipe/common.php';

// Configuration
set('default_stage', 'test');
set('repository', 'git@github.com:derpixler/easy-wordpress-composer-install.git');
