Ravi Lachhman shares his experience comparing the deployment capabilities of Spinnaker and Harness, specifically in deploying an Nginx image into an Amazon EKS cluster. He documents his attempt to install Spinnaker using various resources, including Armory's documentation, but encounters challenges that prevent him from completing the deployment within a reasonable timeframe. Lachhman notes the complexity of setting up Spinnaker, especially in getting the system account to work, which ultimately led him to abandon the effort. In contrast, he successfully deploys the Nginx image using Harness within just five minutes, demonstrating the efficiency and ease of use of Harness in continuous delivery tasks. Lachhman concludes by encouraging others to try Harness's community edition for a similar streamlined deployment experience.
