Docker vs. Spinnaker

You are going to be able to find the most resources and examples using Docker whenever you are working with a container orchestration software like Kubernetes. There will always some entropy when you run in a container, a containerized application will never be as purely performant as an app running directly on the OS. However, in most scenarios this loss will be negligible to the time saved in deployment, monitoring, etc.

Spinnaker suits well for applications which are stateless and can adapt to an immutable architecture of deployment. But for applications which are stateful and cannot afford to spin up new servers for every deployment doesn't go well with Spinnaker. It can handle only deployments which are VM based and cannot support deployments to serverless architecture like AWS Lambda etc.

Incentivized

• Packaging of application to limit the space occupied
• Ease of running the application
• Provide multiple ways to handle the application issues and integration of different components like pipeline, ansible, terraform etc

• Fast deployments.
• Can be integrated with a good variety of other products.
• Also provides some insights from your environment.

Incentivized

• Docker hub image retention policy can be relaxed
• Docker hub policies can be more developer friendly
• Docker CLI help section can be improved
• Image and container storage (local) management can be optimized

Incentivized

• It does NOT support CFN based deployments
• Windows based systems finds it difficult to onboard to Spinnaker.
• Pipeline level access authorisation is not there.
• Support for EBS volume encryption is probably missing.
• Attach/detach EBS volumes during deployments is difficult.
• No support to deploy the artifacts without re-creating the servers. Only pure immutable deployment are allowed.
• Open-source - so good and bad!
• Spinnaker on its own has 10 underlying micro services. Managing Spinnaker needs a focussed platform approach.
• User authentication is easy but authorisation management is not straight forward.

I have been using Docker for more than 3 years and it really simplifies the modern application development and deployment. I like the ability of Docker to improve efficiency, portability and scalability for developers and operations teams. Another reason for giving this rating is because Docker integrates CI/CD pipelines very well

Haven't seen any outages, fatal/unrecoverable errors in my usage so far. Enough said.

Docker Desktop. The CPU high usage is a known issue. Needs fixing. Otherwise, it is great overall. Would not use anything else still.

The reason why we are still using Docker right now is due to that is the best among its peers and suits our needs the best. However, the trend we foresee for the future might indicate Amazon lambda could potentially fit our needs to code enviornmentless in the near future.

Incentivized

• Pipeline Expressiveness • Self-Service/Override • Visibility of Client Teams • Operability of Client Teams - • High-Quality Integrations (AWS, IHP, Google) • Extensibility – (Ability to add code) • The maturity of Deployment Process • Speed/Ease of Onboarding

It is the only tool in our toolset that has not [had] any issues so far. That is really a mark of reliability, and it's a testimony to how well the product is made, and a tool that does its job well is a tool well worth having. It is the base tool that I would say any organisation must have if they do scalable deployment.

Incentivized

• Reduces the number of virtual machine which impacted our quarterly billing
• Using docker with proxy we run multiple application on same port on same host.
• impact on billing is we have to provide docker training to the people who are working on it.

• By using Spinnaker we are able to deploy new versions of our product quickly.
• A deployment takes in average 2 minutes.
• Our investment on Spinnaker was just time learning it.
