I don't like their idea of what a docker-compose replacement should be. And reading issues and limitations about podman pod commands is very discouraging. I would love to hear what others are using and their experiences though. I avoid anything Kubernetes because of a personal bias.

[uponcoffee]

Would you be willing to elaborate on the reason why you avoid kubernetes?

[tonyarkles]

I'm not the OP, but...

Here's the scene: Most of the web projects I work on will never have a billion users. They might have 5, or 10. One or two have thousands. Several of them have 1 (me).

Docker-compose works for me. I set up a container for my backend, a container for whatever's serving the static resources for the frontend, and a container for whatever databases are needed (Postgres, Redis, whatever). The databases get a filesystem volume mount that I can snapshot off the disk with a nightly cron job.

I have a script that will transform a brand shiny new $5/mo DigitalOcean Ubuntu image into a machine with nginx+LetsEncrypt for SSL termination, and with Docker and docker-compose installed (and the Docker port firewalled off, natch). From there, I run "docker-compose up -d" and my project fires up and goes. Maybe I have to edit a line or two in the nginx.conf that my script put in place.

To deploy, I do a local build on my laptop (or Jenkins for a few projects where it makes sense) via a script that pushes the built containers to Docker Hub, and runs docker-compose pull on the host.

This has served me beautifully.

I've looked at Kube more than once. It looks cool for things dramatically bigger than what I'm working on. For something that isn't massive scale, it's bloody complicated. If one of these projects ever gets to the point where a $40/mo DigitalOcean box can't handle the load, I'll probably look at it again. Until then, though, it feels like a very expensive (time-wise) premature optimization.

I like the sound of how you have that set up, do you know any good open source repositories that are designed the way you describe that I could look at for learning purposes?

(I mean, projects that set up containers for backend, database, and front-end servers and push them to digitalocean etc.. I can imagine how each piece works, but I'd love to see how a coherent and manageable project in that style is organized as a whole.)

[tonyarkles]

Hmmmm... I can't say I've ever looked a whole lot. Based on the replies in this thread though, I should probably just take the scripts I've got, make sure there's nothing sensitive in there, and throw them up on Github. Maybe I'll strip my SSH pubkey out of the too, so that we don't end up with a bunch of servers that I can log into :D

[radarsat1]

That would be cool! (And that's a yes for stripping your SSH key ;)

[tonyarkles]

As a tangent... super curious about your username. I've been in the local Radarsat ground terminal and worked on some barely-related projects...

[w-ll]

Seconded, I work on a lot of little toy projects, and host them all on a super cheap vps. Only thing i'd mainly say is different is I have a docker-compose project consisting of jwilder/nginx-proxy, a bind server, and a log processing server. Each project I have to add the virtual network of that composes. But then its all handled.

[unicornfinder]

Out of curiosity, have you ever used Traefik? At work we're using Docker Swarm (because we needed more power than a single server could give us but Kubernetes seemed excessive) with Traefik and it works beautifully.

[team_containous]

Hey Unicornfinder. Please join us at the community forum if you haven't already. And, thanks for the mention! We hope to get to know you more, on the forum. https://community.containo.us

Like I said it's a personal bias, mainly about Google. The only time I had to use it was with RH's cloud and if it wasn't for their good documentation I would have dropped the client. Everytime I looked under the hood it reminded why I hate being a developer around 35% of the time.

[orf]

That’s a rather bizarre reason to avoid a pretty solid system.

[yebyen]

But also a pretty solid testament to the credit of RedHat's documentation, which I'll echo myself. My OpenShift experience is limited to 2017, but I've never heard anything but positive things about OpenShift's documentation, and I heard it has moved a lot closer to mainline Kubernetes since.

[dinkleberg]

As a huge proponent of kubernetes for the enterprise world (a big part of my day job), I won’t touch it for small to medium sized projects.

The cost of running a managed kubernetes is too expensive to justify for the benefits in these cases. And if you choose to self-manage to cut the money cost, it ends up being significantly more expensive from a time and sanity perspective.

[yebyen]

What are the costs of a managed Kubernetes? I don't know if I understand what you mean, because most managed Kubernetes that I know are practically not, or just nominally more expensive in terms of resource cost. Like GKE, AKS, you don't pay for manager nodes, so it's actually a cost savings compared to running your own Kubernetes with kubespray or another method that leaves managing the control plane nodes up to you - managed Kubernetes is actually cheaper, if you're building for high availability.

Are you referring to the cost of migration (since most Kubernetes adopters are probably also learning K8s for the first time as well?)
