    Interne vs. externe Volumina\n\nIn der Regel werden die Volumina von Molek\u00fclen und deren Komplexen durch die van-der-Waals-Radius der Atome bestimmt. Diese Volumina werden als interne Volumina bezeichnet. Externe Volumina hingegen werden durch die van-der-Waals-Radius der Atome plus einem zus\u00e4tzlichen Radius bestimmt, der die Gr\u00f6\u00dfe der L\u00f6sungsmittelmolek\u00fcle ber\u00fccksichtigt.

    Wie man externe Volumes erstellt\n\nIn diesem Abschnitt erfahren Sie, wie Sie externe Volumes erstellen k\u00f6nnen. Externe Volumes sind eine gro\u00dfartige M\u00f6glichkeit, zus\u00e4tzlichen Speicherplatz f\u00fcr Ihre Anwendungen bereitzustellen. Sie k\u00f6nnen sie verwenden, um Daten persistent zu speichern, auch wenn der Container, der die Anwendung ausf\u00fchrt, neu gestartet oder entfernt wird.\n\nSchritt 1: Erstellen Sie ein externes Volume\n\nUm ein externes Volume zu erstellen, verwenden Sie den folgenden Befehl:\n\n```\ndocker volume create \n```\n\nErsetzen Sie `` durch den gew\u00fcnschten Namen f\u00fcr Ihr Volume. Zum Beispiel:\n\n```\ndocker volume create my-volume\n```\n\nSchritt 2: Mounten Sie das Volume in einen Container\n\nSobald Sie ein externes Volume erstellt haben, k\u00f6nnen Sie es in einen Container einbinden. Verwenden Sie dazu den folgenden Befehl:\n\n```\ndocker run -v : \n```\n\nErsetzen Sie `` durch den Namen des von Ihnen erstellten Volumes, `` durch den Pfad, an dem das Volume im Container eingebunden werden soll, und `` durch den Namen des Docker-Images, das Sie verwenden m\u00f6chten. Zum Beispiel:\n\n```\ndocker run -v my-volume:\/app\/data my-image\n```\n\nIn diesem Beispiel wird das Volume `my-volume` in den Container unter dem Pfad `\/app\/data` eingebunden.\n\nSchritt 3: \u00dcberpr\u00fcfen Sie das Volume\n\nUm zu \u00fcberpr\u00fcfen, ob das Volume erfolgreich erstellt und eingebunden wurde, k\u00f6nnen Sie den folgenden Befehl verwenden:\n\n```\ndocker volume ls\n```\n\nDieser Befehl zeigt eine Liste aller verf\u00fcgbaren Volumes an. Sie sollten Ihr erstelltes Volume in der Liste sehen.\n\nFazit\n\nExterne Volumes sind eine leistungsstarke Funktion von Docker, die es Ihnen erm\u00f6glicht, Daten persistent zu speichern und zwischen Containern freizugeben. In diesem Abschnitt haben Sie gelernt, wie Sie externe Volumes erstellen und in Container einbinden k\u00f6nnen.

    Use Cases for External Volumes<\/h2>\n
    Externe Volumes dienen in Docker-Anwendungen verschiedenen Anwendungsf\u00e4llen. Im Folgenden sind einige g\u00e4ngige Szenarien aufgef\u00fchrt, in denen externe Volumes von Vorteil sind:<\/p>\n
    1. Shared Data Between Multiple Applications<\/h3>\n
    When developing microservices or multi-tier architectures, it may be necessary to share data between different applications. External volumes allow you to define a single data source that multiple services can access without duplicating data. For instance, a user-uploaded files Service<\/a><\/span>Service bezeichnet die Handlung, Unterst\u00fctzung oder Hilfe zu leisten, um spezifische Bed\u00fcrfnisse oder Anforderungen zu erf\u00fcllen.

This setup is critical in production environments where data integrity is paramount.<\/p>\n
    3. Umgebungskonsistenz<\/h3>\n
    When working in development, testing, and production environments, external volumes can help ensure that the same data and file structures are used across these environments. By using external volumes, you can maintain consistency in the data your applications rely on, reducing the risk of environment-related issues.<\/p>\n
    4. Data Backup and Migration<\/h3>\n
    External volumes can simplify backup and migration processes. For instance, if you need to migrate an application to a different host or cloud provider, you can manage and back up the external Band<\/a><\/span>Volume is a quantitative measure of three-dimensional space occupied by an object or substance, typically expressed in cubic units.

    Best Practices f\u00fcr die Verwendung externer Volumes\n\nVolumes are a great way to store data outside of containers. They are designed to be independent of the container's lifecycle, so the data stored in them will persist even if the container is deleted. This makes them ideal for storing data that needs to be shared between containers or that needs to be preserved across container restarts.\n\nHowever, there are some best practices that you should follow when using volumes to ensure that your data is safe and secure. Here are some of the most important ones:\n\n1. Use unique volume names: When creating a volume, make sure to give it a unique name that is descriptive of its purpose. This will make it easier to identify and manage the volume later on.\n\n2. Use labels: Labels are key-value pairs that can be attached to volumes to provide additional metadata. They can be used to categorize volumes, track their usage, or provide other useful information. For example, you could use a label to indicate the type of data stored in a volume or the application that uses it.\n\n3. Use volume plugins: Volume plugins are extensions that provide additional functionality for volumes. They can be used to integrate with external storage systems, provide encryption, or add other features. Using a volume plugin can help you take advantage of advanced features and improve the security and reliability of your volumes.\n\n4. Use volume snapshots: Volume snapshots are point-in-time copies of a volume's data. They can be used to create backups, test changes, or recover from data loss. Using volume snapshots can help you protect your data and ensure that you can recover from unexpected events.\n\n5. Use volume encryption: Volume encryption is a feature that encrypts the data stored in a volume. It can help protect your data from unauthorized access and ensure that it remains confidential. Using volume encryption can help you meet compliance requirements and protect sensitive data.\n\n6. Use volume access controls: Volume access controls are rules that determine who can access a volume and what they can do with it. They can be used to restrict access to sensitive data, prevent accidental deletion, or enforce other security policies. Using volume access controls can help you protect your data and ensure that it is only accessed by authorized users.\n\n7. Use volume monitoring: Volume monitoring is the process of tracking the usage and performance of volumes. It can help you identify issues, optimize performance, and ensure that your volumes are being used effectively. Using volume monitoring can help you improve the reliability and efficiency of your volumes.\n\nBy following these best practices, you can ensure that your volumes are safe, secure, and reliable. They can help you protect your data, improve performance, and ensure that your applications run smoothly.<\/h2>\n
    Although external volumes offer great flexibility, there are best practices you should consider to ensure effective management and usage:<\/p>\n
    1. Clear Naming Conventions<\/h3>\n
    Adopt a clear and consistent naming convention for your volumes to avoid confusion. Use names that reflect their purpose and the application they are associated with.<\/p>\n
    2. Dokumenten-Volume-Nutzung<\/h3>\n
    Always document the purpose and intended usage of external volumes, especially in larger teams or when working on open-source projects. This practice helps onboard new team members and maintains clarity.<\/p>\n
    3. Regular Backups<\/h3>\n
    Implementieren Sie eine Backup-Strategie f\u00fcr Ihre externen Volumes, insbesondere f\u00fcr kritische Daten wie Datenbanken. Regelm\u00e4\u00dfige Backups k\u00f6nnen Datenverlust verhindern und die Wiederherstellung im Katastrophenfall erleichtern.<\/p>\n
    4. Monitor Volume Usage<\/h3>\n
    Monitoring the disk usage of your volumes can help identify potential issues before they become critical. Utilize Docker commands to check Band<\/a><\/span>Volume is a quantitative measure of three-dimensional space occupied by an object or substance, typically expressed in cubic units. It is fundamental in fields such as physics, chemistry, and engineering. More \u00bb<\/a><\/span><\/span><\/span><\/span><\/span> sizes and ensure that you have sufficient disk space available.<\/p>\n
    5. Isolate Critical Data<\/h3>\n
    Bei der Verwendung externer Volumes f\u00fcr sensible Daten sollten Sie erw\u00e4gen, diese auf dedizierten Speicherl\u00f6sungen zu isolieren, um Sicherheit und Leistung zu verbessern.<\/p>\n
