Derri\u00e8re ces deux lettres se cachent des pratiques accessibles \u00e0 toute \u00e9quipe web, dont le b\u00e9n\u00e9fice est simple : livrer plus vite, avec moins d&rsquo;erreurs.<\/p>\n\n<h2>CI : l&rsquo;int\u00e9gration continue<\/h2>\n<p>L&rsquo;int\u00e9gration continue (Continuous Integration) consiste \u00e0 fusionner fr\u00e9quemment le travail de chacun dans un tronc commun, en v\u00e9rifiant automatiquement que rien ne casse. \u00c0 chaque modification, une suite de tests s&rsquo;ex\u00e9cute : compilation, tests unitaires, contr\u00f4les de qualit\u00e9. Les probl\u00e8mes sont d\u00e9tect\u00e9s t\u00f4t, quand ils sont encore faciles \u00e0 corriger.<\/p>\n\n<h2>CD : livraison et d\u00e9ploiement continus<\/h2>\n<p>Le CD prolonge la CI vers la mise en production. On distingue deux nuances :<\/p>\n<ul>\n<li>La <strong>livraison continue<\/strong> (Continuous Delivery) pr\u00e9pare automatiquement chaque version pour la production, la mise en ligne finale restant d\u00e9clench\u00e9e manuellement.<\/li>\n<li>Le <strong>d\u00e9ploiement continu<\/strong> (Continuous Deployment) va jusqu&rsquo;au bout : toute modification qui passe les tests part automatiquement en production.<\/li>\n<\/ul>\n\n<h2>Pourquoi \u00e7a change tout<\/h2>\n<p>Sans CI\/CD, la mise en production est un \u00e9v\u00e9nement rare, risqu\u00e9 et stressant : on accumule des changements, on croise les doigts. Avec CI\/CD, on livre par petites touches fr\u00e9quentes et v\u00e9rifi\u00e9es. Chaque changement est petit, donc son risque est faible, et l&rsquo;origine d&rsquo;un \u00e9ventuel probl\u00e8me est facile \u00e0 identifier.<\/p>\n\n<h2>L&rsquo;anatomie d&rsquo;un pipeline<\/h2>\n<p>Un pipeline CI\/CD encha\u00eene des \u00e9tapes automatis\u00e9es : r\u00e9cup\u00e9ration du code, installation des d\u00e9pendances, ex\u00e9cution des tests, construction de l&rsquo;application, puis d\u00e9ploiement. Si une \u00e9tape \u00e9choue, le pipeline s&rsquo;arr\u00eate et alerte l&rsquo;\u00e9quipe avant que le probl\u00e8me n&rsquo;atteigne les utilisateurs.<\/p>\n\n<h2>Commencer sans se noyer<\/h2>\n<p>Inutile de tout automatiser d&#8217;embl\u00e9e. Commencez par la CI : lancez vos tests automatiquement \u00e0 chaque modification. Ajoutez ensuite le d\u00e9ploiement automatis\u00e9 vers un environnement de test, puis vers la production quand la confiance est \u00e9tablie. Les plateformes modernes, dont l&rsquo;App Platform d&rsquo;OVHcloud, int\u00e8grent ces m\u00e9canismes, ce qui abaisse fortement la barri\u00e8re d&rsquo;entr\u00e9e pour les petites \u00e9quipes.<\/p>","protected":false},"excerpt":{"rendered":"<p>Int\u00e9gration continue et d\u00e9ploiement continu : deux pratiques qui automatisent tests et mises en production pour livrer plus vite et plus s\u00fbrement.<\/p>\n","protected":false},"author":1,"featured_media":1113,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[3],"tags":[],"class_list":["post-113","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-developpement-devops"],"_links":{"self":[{"href":"https:\/\/webhostingproduct.ovh\/index.php?rest_route=\/wp\/v2\/posts\/113","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/webhostingproduct.ovh\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/webhostingproduct.ovh\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/webhostingproduct.ovh\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/webhostingproduct.ovh\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=113"}],"version-history":[{"count":0,"href":"https:\/\/webhostingproduct.ovh\/index.php?rest_route=\/wp\/v2\/posts\/113\/revisions"}],"wp:attachment":[{"href":"https:\/\/webhostingproduct.ovh\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=113"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/webhostingproduct.ovh\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=113"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/webhostingproduct.ovh\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=113"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
