When running in > rootless mode, Docker is started as a user-mode systemd service, and uses > files stored in each users' home directory in > ~/.config/systemd//docker.service.d/. In addition, systemctl must > be executed without sudo and with the --user flag. Select the \"Rootless > mode\" tab if you are running Docker in rootless mode.\n\nCreate a systemd drop-in directory for the docker service\n\nBounded code example (external data; do not execute automatically):\n```console\n   $ sudo mkdir -p /etc/systemd/system/docker.service.d\n```\n\nCreate a file named /etc/systemd/system/docker.service.d/http-proxy.conf that adds the HTTP_PROXY environment variable\n\nBounded code example (external data; do not execute automatically):\n```systemd\n   [Service]\n   Environment=\"HTTP_PROXY=http://proxy.example.com:3128\"\n```\n\nTo proxy HTTPS requests, set the HTTPS_PROXY environment variable\n\nBounded code example (external data; do not execute automatically):\n```systemd\n   [Service]\n   Environment=\"HTTPS_PROXY=http://proxy.example.com:3128\"\n```\n\nMultiple environment variables can be set; to set both an HTTP and an HTTPS proxy;\n\nBounded code example (external data; do not execute automatically):\n```systemd\n   [Service]\n   Environment=\"HTTP_PROXY=http://proxy.example.com:3128\"\n   Environment=\"HTTPS_PROXY=http://proxy.example.com:3128\"\n```\n\n> [!NOTE] > > Special characters in the proxy value, such as #?!()[]{}, must be double > escaped using %%.
