![]() ![]() You can then use the address of any node in your cluster (with the agent port) inside the Agent URL field. The Agent implements the Trust On First Use (TOFU) principle, so only the first Portainer to connect will be able to use it, but you want to avoid an attacker beating you to it. Therefore it is highly recommended to use the AGENT_SECRET environment variable to define a shared secret, see Shared secret. Publishing the Agent port 9001 in host mode basically means opening up this port in the Docker hosts firewall for all interfaces. Note: Please be aware that this could potentially open up the Agent for use by anybody in case the Docker host is reachable from the internet. Other communication occurs via the native operating system processes (for example NetBIOS over TCP/IP). mount type=bind,src=//var/lib/docker/volumes,dst=/var/lib/docker/volumes \ The diagram below shows the separated installation and the used ports: The tables below list all possible network communication ports used when ESET PROTECT and its components are installed in your infrastructure. mount type=bind,src=//var/run/docker.sock,dst=/var/run/docker.sock \ publish mode=host,target=9001,published=9001 \ In all bringing a better Docker user experience when managing Swarm clusters. As aforementioned, this means that you only need to execute one Docker API request to retrieve all these resources from every node inside the cluster. ![]() All while keeping the Docker API request format. ![]() The purpose of the agent aims to allow previously node specific resources to be cluster-aware. When you, for example, want to list all the volumes available on a node inside your cluster, you will need to send a query to that specific node. Cluster-aware means that you can query for a list of services or inspect a task inside any node on the cluster, as long as you’re executing the Docker API request on a manager node.Ĭontainers, networks, volumes and images are node specific resources, not cluster-aware. of any employer who fails to comply with section 32(a) 33 USC 932(a). It also adds services, tasks, configs and secrets which are cluster-aware resources. This Act may be cited as Longshore and Harbor Workers Compensation Act. The user interactions with specific resources (containers, networks, volumes and images) are limited to those available on the node targeted by the Docker API request.ĭocker Swarm mode introduces a concept which is the clustering of Docker nodes. The Portainer Agent is a workaround for a Docker API limitation when using the Docker API to manage a Docker environment. ![]()
