Docker Desktop install, WSL 2, and data safety

Basic check order

1. Choose the platform and backend before downloading. Docker's current Windows page requires WSL 2.1.5 or later for the default x86_64 WSL backend, Windows 10 64-bit Enterprise, Pro, or Education 22H2 build 19045, or Windows 11 64-bit Enterprise, Pro, or Education 23H2 build 22631 or later. Virtualization and the WSL feature must be available. Docker Desktop is not supported on Windows Server; Windows containers also have stricter edition and installation-mode requirements.
2. On macOS, confirm that the computer runs the current or one of the two previous major macOS releases and has at least 4 GB of RAM. Select the official Apple-silicon or Intel installer for the actual processor. Rosetta 2 is recommended on Apple silicon for optional AMD64 command-line tools, but Docker says it is no longer a universal requirement.
3. Start from Docker's Windows or Mac installation documentation, not a copied asset URL or a generic container-tool bundle. Windows now distinguishes a recommended per-user installation from an all-users installation: per-user mode has a smaller privileged footprint and normally uses WSL 2, while all-users mode requires administrator rights and is needed for Hyper-V or Windows-container scenarios. Managed Mac fleets should review Docker's documented PKG route rather than repackaging the consumer DMG.
4. Check subscription eligibility before workplace deployment. Docker's installation pages state that commercial use in an enterprise with more than 250 employees or more than 10 million US dollars in annual revenue requires a paid subscription; government use also requires a paid plan. Preserve the current official terms or purchasing decision with the device-management record instead of treating a public download as unrestricted business permission.
5. Decide what the engine may reach. Enable WSL integration only for distributions that need Docker commands, keep repositories and bind mounts in approved locations, and review access to source code, SSH keys, registry credentials, environment files, host sockets, local ports, and shared folders. A container is not a trust boundary for an unreviewed image or script, and mounting a host directory gives the workload the access allowed by that mount.
6. Set resource, startup, update, networking, and file-sharing choices deliberately. Avoid enabling the unauthenticated TCP daemon option: Docker warns that exposing localhost port 2375 without TLS can enable remote-code-execution attacks. On shared or managed devices, document which user owns Docker Desktop, whether it starts at sign-in, which WSL distributions are integrated, where the virtual disk lives, and who controls registry sign-in and extensions.
7. Back up the reproducible parts before a major update, reset, migration, or uninstall. Keep Dockerfiles, Compose files, source, configuration templates, and secret references in approved version control; back up named volumes separately; and save or push only images that are genuinely needed. Docker notes that committing a container can preserve environment variables in the image while omitting attached volume data, so inspect for secrets and registry visibility before moving an image.
8. Troubleshoot from the least destructive option to the most destructive. First capture the exact error, OS and WSL versions, free disk space, backend, and relevant redacted logs; then check virtualization, WSL status, conflicting Docker Engine or CLI installations inside a WSL distribution, corporate proxy or VPN behavior, and Docker's known guidance. Restart only the app before considering clean/purge or factory reset, because Docker documents those options as data- or settings-destructive.

Cautions and operating tips

• WSL integration is selective. Docker Desktop runs in its own docker-desktop distribution and interacts with another WSL distribution only after integration is enabled, but Windows processes can still access WSL files through the normal WSL interoperability model. Keep secrets out of broadly readable working trees and do not assume a Linux path is invisible to the Windows host.
• Do not install Docker Engine or a second Docker CLI directly inside an integrated WSL distribution just because an old tutorial says to do so. Docker's WSL guidance warns that running those alongside Docker Desktop can conflict. Decide whether the workstation uses Docker Desktop integration or a separate Linux engine, then document one ownership model.
• Treat images, build contexts, Compose files, extensions, and registry credentials as software supply-chain inputs. Prefer publisher-controlled registries and pinned image versions or digests where the project supports them; review Dockerfiles before building; and never place long-lived tokens in image layers, Compose files, terminal history, or support screenshots.
• A factory reset is not an ordinary repair step. It can remove local images, containers, Kubernetes resources, volumes, and settings depending on the selected action. Confirm what is reproducible, what is backed up, and what belongs to a customer or employer before using Clean / Purge data or Reset to factory defaults.
• Diagnostics can contain host paths, usernames, container names, registry names, proxy details, log excerpts, and other environment information. Upload a diagnostic bundle only through Docker's documented support path and under the organization's support policy; do not paste raw logs, tokens, environment files, or proprietary image names into a public issue.
• If Docker Desktop does not fit the license, platform, or security model, compare a supported Docker Engine installation on Linux, Podman Desktop, a managed remote development environment, or an organization-provided container host. Compare daemon privileges, image compatibility, networking, volume behavior, update ownership, licensing, and team support rather than choosing solely by command similarity.
• AppVeriq Guide does not host, mirror, modify, or redistribute Docker installers, images, extensions, or registry content. Complete installation and updates through Docker-controlled pages or an organization-approved deployment channel.
