Here we will give details about what is Docker file, it’s content along the deployment steps to deploy the application into AWS.

  1. Login in you AWS Account.

  2. At first you need to create an instance in AWS or GCP. I have some articles on how you can create instance on AWS here.

  3. Next, we need to connect to that instance. There are many ways to connect to an instance like Putty / Terminal or Console form AWS or GCP. If you want to connect from Putty then follow my other article here.

  4. Docker file: Pull the latest(1.15.3) nifi docker image from https://hub.docker.com/r/apache/nifi/ in your local system.

    Code Block
    docker pull apache/nifi:1.15.3 
  5. Run the pulled docker image

    1. Secure Mode(with https)

      Code Block
      docker run -p 8443:8443 -e SINGLE_USER_CREDENTIALS_USERNAME=admin -e SINGLE_USER_CREDENTIALS_PASSWORD='admin@123' -e NIFI_WEB_HTTPS_PORT='8443' -e NIFI_WEB_PROXY_HOST='192.168.100.100:8443' apache/nifi:1.15.3
      1. When we will use secure mode then few useful environment variables are

        1. custom login username and password set SINGLE_USER_CREDENTIALS_USERNAME and SINGLE_USER_CREDENTIALS_PASSWORD.

        2. Replace NIFI_WEB_PROXY_HOST value with your ec2 Public IPv4 address value

        3. If username/password not set executed in command then It will create some auto-generated credentials and we'll see them in the nifi-app.log.

          Code Block
          Generated Username [USERNAME]
          Generated Password [PASSWORD] 

           

        4. NIFI_WEB_HTTPS_PORT secure port no, NIFI_WEB_HTTPS_HOST secure host ip or domain name.

        5. open nifi url in browser https://instance-host:8443/nifi

    2. Unsecure Mode(with http)

      Code Block
      docker run -p 8080:8080  -e NIFI_WEB_HTTP_PORT='8080' apache/nifi:1.15.3

       

      1. NIFI_WEB_HTTP_PORT unsecure port no, NIFI_WEB_HTTP_HOST secure host ip or domain name.

      2. open nifi url in browser http://instance-host:8080/nifi
