Docker vs. Rocket DevOps

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.

Rocket Aldon is perfect for simple changes to traditional IBM i development using RPGLE, CL, and DDS. It is great for finding related objects that are referenced in many locations and helping recompile all of these objects. However, Aldon has a particularly hard time with SQL views. For some reason, it is determined to lock every table related to a view even though this is not required by the operating system. Whenever one view references another view, you are always in danger of losing a view permanently if you didn't check it out and promote it. To clarify, imagine you created a view CUSTOMER_INFO. Then you make another view called CUSTOMER_SHIPMENTS that joins the CUSTOMER_INFO to a shipping table. If you ever change CUSTOMER_INFO and then promote it, there is a good chance that Aldon will delete the CUSTOMER_SHIPMENTS view and you will not get a single warning. It doesn't happen every time but when it does you are going to have a real mess on your hands.

Based on current integration with our release process, we will need to keep this for the future.

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.

Support is hit and miss. Sometimes they give some great assistance and sometimes they are no help at all. It always seems like they can't replicate the problem but then they never try to get on our system to do deeper research. It's kind of frustrating dealing with them. Also, the website isn't that helpful.

We need a solution where initially we can use an OS to trigger our pipeline to be used by terraform and then later in ansible. After doing all work it automatically get exited and we can reclaim the space of our VM. So we created a gitlab pipeline and at the initial stage we defined a docker file which will be our base image and we performed all our activities inside that image to build infrastructure using terraform. Integration we have done in our gitlab pipeline and finally we remove the docker image so that the space can be reclaimed immediately.

There are not a lot of CMS solutions for the IBM i server. Midrange Dynamics MDCMS is definitely one to consider. It seems very similar to Aldon Rocket and has a lot more functionality. I haven't used it but I have been to a demo and it looks promising. It seems a lot more intuitive and the promotions seem easier. However, that was a demo environment and even then it crashed so there's that to consider....

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.

• With Docker adoption, were able to reduce 40% of the time taken to complete workspace setup
• Provided the environment packaging / configurability capability which enabled resource sharing and interoperability across teams
• Were able to leverage off the shelf images provided by leading product companies which increased reliability and security exponently

• Software promotion is much easier and doesn't require custom coding.
• Developers can work collaboratively with less overlap.
• Developers can find objects faster and research code more thoroughly.
