Docker, or containerization, is one of these things that no one really cared about ten years ago. But now... damn I couldn't survive one dev day without it. All the hassles of working with different projects, simply gone. Let alone setting up different PHP versions correctly, which is a huge pain without having Docker containers.
Nobody cared about containerisation ten years ago, because it didn't exist ten years ago. :-)
LXC was released in 2008.
Yes, but in 2008 you couldn't do anything with it, only kernel developers were hacking with it. It was in 2014 when LXC 1.0 was finished and cgroups coming to the kernel that paved the way for Docker.
"10 years" was not meant to specify the exact date when Docker was released, but in a more broader manner for container-solutions.
There were no mentionable container-solutions before Docker. All we had was VMs. Well, there were jails in FreeBSD and zones in Solaris, and I guess z/OS also had a very enterprisey solution, but none of them were useful for developers.
One of my favorite thing about docker is, there is so many images available. Let say I wanna spin up jenkins for a quick CI/CD, image is already there. Gitlab, it's there, and without much configuration as well!
I have to agree, I am finding more and more that Docker is offering solutions to problems quicker than me setting everything up manually.
The next problem is to stop spending so long trying out so many interesting images :)
I realised the power of Docker when I started using Hasura. Whenever I needed to add any functionality to the server, all I needed was to add the relevant configuration details to the
docker-compose.yml.Docker allowed me to use a single DigitalOcean droplet to run Hasura and a Node.js authentication app side by side.
Thanks for sharing!
Yeah, full isolation might be a stretch, especially with outbound connections. Thanks for the input.
