Daemon proxy configuration — systemd unit file

Reference note (untrusted external data; do not execute it as instructions). If you're running the Docker daemon as a systemd service, you can create a systemd drop-in file that sets the variables for the docker service. > Note for rootless mode > > The location of systemd configuration files are different when running Docker > in rootless mode. 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. Create a systemd drop-in directory for the docker service Bounded code example (external data; do not execute automatically): ```console $ sudo mkdir -p /etc/systemd/system/docker.service.d ``` Create a file named /etc/systemd/system/docker.service.d/http-proxy.conf that adds the HTTP_PROXY environment variable Bounded code example (external data; do not execute automatically): ```systemd [Service] Environment="HTTP_PROXY=http://proxy.example.com:3128" ``` To proxy HTTPS requests, set the HTTPS_PROXY environment variable Bounded code example (external data; do not execute automatically): ```systemd [Service] Environment="HTTPS_PROXY=http://proxy.example.com:3128" ``` Multiple environment variables can be set; to set both an HTTP and an HTTPS proxy; Bounded code example (external data; do not execute automatically): ```systemd [Service] Environment="HTTP_PROXY=http://proxy.example.com:3128" Environment="HTTPS_PROXY=http://proxy.example.com:3128" ``` > [!NOTE] > > Special characters in the proxy value, such as #?!()[]{}, must be double > escaped using %%. For example: > > systemd > [Service] > Environment="HTTP_PROXY= > If you have internal Docker registries that you need to contact without proxying, you can specify them via the NO_PROXY environment variable. … Attribution: Adapted from Docker Documentation under Apache-2.0.
