Using a load balancer outside of the Swarm allows an easy way to connect to your containers without having to worry about the cluster nodes. For consistency, the load balancer will be deployed on its own single node swarm. Open an SSH connection to your load balancer server and initialize a new. Hi everyone today we’ll learnHowto configure Nginx as Rreverse Proxy / Load balancer with Weave and Docker Weave creates a virtual network that connects Docker containers with each other, deploys across multiple hosts and enables their automatic discovery.

Hi everyone today we’ll learnHowto configure Nginx as Rreverse Proxy / Load balancer with Weave and Docker Weave creates a virtual network that connects Docker containers with each other, deploys across multiple hosts and enables their automatic discovery. It allows us to focus on developing our application, rather than our infrastructure. It provides such an awesome environment that the applications uses the network as if its containers were all plugged into the same network without need to configure ports, mappings, link, etc. The services of the application containers on the network can be easily accessible to the external world with no matter where its running. Here, in this tutorial we’ll be using weave to quickly and easily deploy nginx web server as a load balancer for a simple php application running in docker containers on multiple nodes in Amazon Web Services. Here, we will be introduced to WeaveDNS, which provides a simple way for containers to find each other using hostname with no changes in codes and tells other containers to connect to those names. Here, in this tutorial, we will use Nginx to load balance requests to a set of containers running Apache. Here are the simple and easy to do steps on using Weave to configure nginx as a load balancer running in ubuntu docker container. Settting up AWS Instances First of all, we’ll need to setup Amazon Web Service Instances so that we can run docker containers with Weave and Ubuntu as Operating System.

We will use the to setup and configure two AWS EC2 instances. Here, in this tutorial, we’ll use the smallest available instances, t1.micro. We will need to have a valid Amazon Web Services account with AWS CLI setup and configured. We’ll first gonna clone the repository of weave from the github by running the following command in AWS CLI.

$ git clone $ cd weave-gs/aws-nginx-ubuntu-simple After cloning the repository, we wanna run the script that will deploy two instances of t1.micro instance running Weave and Docker in Ubuntu Operating System. $ sudo./demo-aws-setup.sh Here, for this tutorial we’ll need the IP addresses of these instances further in future. These are stored in an environment file weavedemo.env which is created during the execution of the demo-aws-setup.sh. To get those ip addresses, we need to run the following command which will give the output similar to the output below. How to put in a texture pack for minecraft on mac.

$ cat weavedemo.env export WEAVE_AWS_DEMO_HOST1=52.26.175.175 export WEAVE_AWS_DEMO_HOST2=52.26.83.141 export WEAVE_AWS_DEMO_HOSTCOUNT=2 export WEAVE_AWS_DEMO_HOSTS=(52.26.175.175 52.26.83.141) Please note these are not the IP addresses for our tutorial, AWS dynamically allocate IP addresses to our instances. As were are using a bash, we will just source this file and execute it using the command below. ./weavedemo.env 2. Launching Weave and WeaveDNS After deploying the instances, we’ll want to launch weave and weavedns on each hosts. Weave and weavedns allows us to easily deploy our containers to a new infrastructure and configuration without the need of changing the codes and without the need to understand concepts such as ambassador containers and links. Here are the commands to launch them in the first host. Ssh -i weavedemo-key.pem $WEAVE_AWS_DEMO_HOST1 $ sudo weave launch $ sudo weave launch-dns 10.2.1.1/24 Next, we’ll also wanna launch them in our second host.
