Comment fonctionne Docker Engine\n\nDocker Engine est un logiciel client-serveur avec les composants majeurs suivants :\n\n- Un serveur qui est un type de programme de longue dur\u00e9e appel\u00e9 d\u00e9mon de processus (la commande dockerd).\n- Une API REST qui sp\u00e9cifie les interfaces quels programmes peuvent utiliser pour parler au d\u00e9mon et lui indiquer ce qu'il doit faire.\n- Un client de ligne de commande (CLI) (la commande docker).\n\nLe CLI utilise l'API Docker pour contr\u00f4ler ou interagir avec le d\u00e9mon Docker via des scripts ou des commandes CLI directes. De nombreuses autres applications Docker utilisent l'API et la CLI sous-jacentes.\n\nLe d\u00e9mon cr\u00e9e et g\u00e8re les objets Docker tels que les images, les conteneurs, les r\u00e9seaux et les volumes.\n\nRemarque : Le d\u00e9mon Docker et le client Docker peuvent s'ex\u00e9cuter sur le m\u00eame syst\u00e8me, ou vous pouvez vous connecter \u00e0 un d\u00e9mon Docker distant.

More \u00bb<\/a><\/span><\/span><\/span><\/span><\/span> access and should operate in complete isolation.<\/p>\n

    Volumes et donn\u00e9es persistantes<\/h2>\n

    One of the limitations of containers is that they are ephemeral by nature. When a conteneur<\/a><\/span>Containers are lightweight, portable units that encapsulate software and its dependencies, enabling consistent execution across different environments. They leverage OS-level virtualization for efficiency. More \u00bb<\/a><\/span><\/span><\/span><\/span><\/span> is removed, any data stored within it is also lost. To address this, Docker provides volumes and bind mounts for persistent data storage.<\/p>\n

    1. Volumes<\/h3>\n

    Volumes are managed by Docker and are stored outside the container’s filesystem. They are designed for persistent data and can be shared among multiple containers. Volumes are preferable for data that needs to persist beyond the lifecycle of a single conteneur<\/a><\/span>Containers are lightweight, portable units that encapsulate software and its dependencies, enabling consistent execution across different environments. They leverage OS-level virtualization for efficiency. More \u00bb<\/a><\/span><\/span><\/span><\/span><\/span> and are easily backed up and restored.<\/p>\n

    2. Bind Mounts<\/h3>\n

    Bind mounts allow you to specify a path on the host filesystem to be mounted into a conteneur<\/a><\/span>Containers are lightweight, portable units that encapsulate software and its dependencies, enabling consistent execution across different environments.
