Then test by running hello-world again without sudo. Logout, then log back in to make sure the membership is reevaluated (su – $USER). # reevaluate group memberships without exiting # group already created, but go ahead and make sure If you don’t want to force sudo access, then you can create a ‘docker’ group and add your user to it. That is because the Docker daemon binds to a unix socket which is owned by root. You have have noticed that you had to run docker with sudo in the hello-world test above. The Docker daemon streamed that output to the Docker client, which sent it to your terminal. The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading.Ĥ. The Docker daemon pulled the "hello-world" image from the Docker Hub.ģ. The Docker client contacted the Docker daemon.Ģ. To generate this message, Docker took the following steps:ġ. This message shows that your installation appears to be working correctly. The docker run command from above should return a message like: Hello from Docker!

Sudo systemctl enable docker Validate Install # version installed Systemd will already have the service configured to start on boot, but if you want to check: # check status The docker engine logs should report “Started Docker Application Container Engine”. This should have installed docker which is running under systemd. Sudo apt-get install docker-ce docker-ce-cli containerd.io

Check the IP address of the peer is correct and check that Calico is using the correct local IP address (set in the network-environment file above).Docker is a container platform that streamlines software delivery and provides isolation, scalability, and efficiency with less overhead than OS level virtualization. If the “Info” column shows “Active” or some other value then Calico is having difficulty connecting to the other host. | Peer address | Peer type | State | Since | Info | The master requires the root CA public key, ca.pem the apiserver certificate, apiserver.pem and its private key, apiserver-key.pem.Ĭreate the file openssl.cnf with the following contents.Ĭalico-node container is running.

If this overlaps with your host subnet, you will need to configure Calico to use a different IP pool. This guide uses 192.168.0.0/16 as the subnet from which pod IP addresses are assigned.This guide assumes a DHCP server on your network to assign server IPs.

All machines should have connectivity to each other and the internet.To install Docker on Ubuntu, follow these instructions.All machines should have Docker >= 1.7.0 installed.Ubuntu 15.04 supports systemd natively as do a number of other Linux distributions. This guide uses systemd for process management.We’ll run Calico’s etcd cluster on the master and install the Calico daemon on the master and nodes. This guide will set up a simple Kubernetes cluster with a single Kubernetes master and two Kubernetes nodes.

To install Calico on an existing Kubernetes cluster, or for more information on deploying Calico with Kubernetes in a number of other environments take a look at our supported deployment guides. For more information on Project Calico, visit and the calico-containers repository.

This document describes how to deploy Kubernetes with Calico networking from scratch on bare metal Ubuntu.
