![]() As on most systems /usr/local/bin is on the PATH by default, and so Docker Desktop creates symlinks for all Docker binaries in it. Docker Desktop ensures the Docker CLI is on your PATH without having to reconfigure shells, log out then log back in for example. The Docker binaries are installed by default in /Applications/Docker.app/Contents/Resources/bin. Following the principle of least privilege, this approach allows root access to be used only for the operations for which it is absolutely necessary, while still being able to use Docker Desktop as an unprivileged user.Īll privileged operations are run using the privileged helper process. For subsequent runs, root privileges aren’t required. The first time that Docker Desktop is launched you receive an admin prompt to grant permission for the installation of the privileged helper service. Versions prior to 4.15 of Docker Desktop for Mac require root access to be granted on the first run. Securely caching the Registry Access Management policy which is read-only for the developer.ĭepending on which version of Docker Desktop for Mac is used, privileged access is granted either during installation, first run, or only when it is needed.Defining the DNS name allows Docker to share Kubernetes contexts with containers. Some old macOS installs do not have localhost in /etc/hosts, which causes Docker to fail. Ensuring localhost and are defined in /etc/hosts.The so-called “privileged ports” are not generally used as a security boundary, however OSes still prevent unprivileged processes from binding them which breaks commands like docker run -p 127.0.0.1:80:80 docker/getting-started. Binding privileged ports that are less than 1024.However, certain functionalities are required for Docker Desktop to perform a limited set of privileged configurations such as: Permission requirementsĭocker Desktop for Mac is run as an unprivileged user. It also provides clarity on running containers as root as opposed to having root access on the host.
