K8s

New Infrastructure

To setup new AWS infrastructure, follow below steps:

1. To create base infrastructure using Magikube please refer Create Project guide.
2. Select aws from the options in Select a Cloud Provider prompt.
3. If you have setup a default region then Select a Region will show it. If that is the region you want to use then move to next step, otherwise you can change to region of your choice.
4. Use k8s for Select a Cluster Type.
5. Validate or update AWS profile name to be used in Enter AWS profile to use.
6. Select your code repository provider in Source code repository.
7. If AWS profile name does not exist then magikube will create a new profile with you. It will need AWS Access Key ID and AWS Secret Access Key.
8. Which environment are you creating. Make selection in Select an Environment.
9. If you are creating a non-production environment, then select one or more lifecyles in Select Lifecycle(s).
10. Enter a domain name in the Enter the Domain Name prompt.
11. To create applications, please refer Apps Guide.

Post Deployment Setup for K8s

1. Using terminal ssh into your master server using command

ssh {{ project_name }}-{{ environment }}-master

2. Execute command to get the list of namespaces

kubectl get namespace

3. Execute command to list all the service running

kubectl get svc -n {{ project_name }}-{{ environment }}-app

4. Execute command and fetch the frontend(Eg: react) IP Value. Here frontend_app is the name of frontend service from step 3.

kubectl get {{ frontend_app }} -n {{ project_name }}-{{ environment }}-app -o jsonpath='{.spec.clusterIP}'

5. Create a file i.e. /etc/nginx/sites-available/application-nginx.conf using below content and replace the value for {{ hostname }} and {{ frontend_service_ip }}

   ## server configuration for Application
server {
    listen 80;
    server_name {{ hostname }};

    if ($http_x_forwarded_proto = '') {
        set $http_x_forwarded_proto  $scheme;
    }

    ## Application specific logs
    chunked_transfer_encoding on;
    client_max_body_size 0;

    location / {
        proxy_read_timeout  2400s;
        proxy_pass_header   Server;
        proxy_cookie_path   ~*^/.* /;
        proxy_pass          http://{{ frontend_service_ip }}:80;  
        proxy_next_upstream error timeout non_idempotent;
        proxy_next_upstream_tries    1;
        proxy_set_header    X-Forwarded-Port  $server_port;
        proxy_set_header    X-Forwarded-Proto $http_x_forwarded_proto;
        proxy_set_header    Host              $http_host;
        proxy_set_header    X-Forwarded-For   $proxy_add_x_forwarded_for;
    }
}

6. Create a symlink for the nginx configurations using command

sudo ln -s /etc/nginx/sites-available/application-nginx.conf /etc/nginx/sites-enabled/application-nginx.conf

7. Restart Niginx using command

sudo systemctl reload nginx
