Elles peuvent d\u00e9pendre de bases de donn\u00e9es, de syst\u00e8mes de fichiers ou de m\u00e9canismes de stockage sp\u00e9cifiques qui ne sont pas compatibles avec les environnements containeris\u00e9s. De plus, la persistance des donn\u00e9es pose un d\u00e9fi dans Docker, car les conteneurs sont par nature \u00e9ph\u00e9m\u00e8res.<\/p>\n<h4>Solution : Cartographie du volume<\/h4>\n<p>Pour g\u00e9rer efficacement les donn\u00e9es, les d\u00e9veloppeurs peuvent utiliser des volumes Docker ou des montages de liaison pour persister les donn\u00e9es en dehors des conteneurs.
