Ok but containers generally have a lot less dependencies. If you are making your own images, then you know exactly how to rebuild them. In the event something happens, it makes it much easier to get up and running again and also remember what you did to get the service running. The only other thing that would be better is Nix.
If you use an image that someone is maintaining, this makes it even easier and there are services out there that will keep your containers up to date when a new image is available. You can also just automate your image builds to run nightly and keep it up to date.
There are a few services out there that do this. They are basically job tracking sites, but a lot of them now use something like chatgpt to tailor your resume to a job description. I do recommend these services to track jobs you applied to, but they are not always the best in rewriting your resume.
One thing I have done is create a section of skills that closely match the jobs I am applying for. You can then use chatgpt API and create a prompt. This makes it easier so that all you need to do is give it the job description and it will tailor those skills sets to the job and I then just copy and paste that into my resume.
