There is an official documentation describes how to Configure where the Docker daemon listens for connections.Ĭonfiguring Docker to listen for connections using both the systemd unit file and the daemon.json file causes a conflict that prevents Docker from starting.Ĭonfiguring remote access with systemd unit file This involves using a DOCKER_HOST value of E.g. Note that with docker versions 18.09 and above on the client (both where you run your command and the remote node), you can use ssh instead of configuring TLS. The docker API ports are frequently scanned on the internet, and you will find malware installed on your host in a short while if you ever skip this configuration step.įull details on how to configure the TLS keys for client and server can be found at:
#ENABLE DOCKER REMOTE API PASSWORD#
If you prefer ssh over telnet, or if you prefer having a password for your root account, then you must configure TLS. If you do not configure mutual TLS between client and server, and you open docker to listen on the network, you are running the equivalent of an open telnet server with root logins allowed without a password. One extremely important part of the above config file are the TLS settings. "tlskey": "/etc/docker/certs/host-key.pem",įor your purposes, you only need the line in there to set the hosts. "tlscert": "/etc/docker/certs/host-cert.pem", here's an example /etc/docker/daemon.json: , Once done, you can override every setting from /etc/docker/daemon.json which is used by docker, and depending on the setting, can be reloaded without restarting the daemon.

That override simply unsets all of the command line flags to the dockerd daemon from systemd. here is my standard /etc/systemd/system//nf: To make your own changes to a systemd unit file that persist, you can create a unit file in /etc/systemd/system//, e.g. If you use this, your changes will be lost.

#ENABLE DOCKER REMOTE API INSTALL#
The /lib/systemd directory is where packages will install their systemd files, and they will overwrite any changes there on upgrade. If you install docker directly from Docker's repositories, this directory will not be used. The /etc/default directory is where distribution maintainers put their configuration files.

What did I miss out? What configuration in what file exposes the API over TCP? docker -H tcp://:2375 infoĬannot connect to the Docker daemon at tcp://:2375. I cannot even connect to the local node by passing the IP. I restarted the docker service, logged out and logged in multiple times in the process, but still cannot connect to the remote node. I also modified /etc/init.d/docker and /etc/init/nf to include DOCKER_OPTS="-H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock". However I cannot access any docker nodes remotely. I have added myself to the docker group and can access docker by SSHing into the nodes. I tried using the command line to connect to remote docker nodes, but got a message Cannot connect to the Docker daemon at tcp://. I am using portainer and am unable to manage remote endpoints.
