Tilt: dev environment as code

Interesting to see this pop up here! I’ve been using Tilt for multiple years now but the pace of development seems to have slowed down after the Docker acquisition. I love how Tilt enables creating a local development environment that lets my services run the same in production , test and development. Greatly simplifies my service code and improved my quality. In particular, I’d love to see Tilt be better around handling things like CRDs (there’s no way to mark a k8s_yaml as depending on a CRD being available, a frequent source of broken tilt up invocations). Having said that, the first thing I do, when working on any new project, is to get “tilt up” working. Things I’ve used for testing include: eBPF-based collectors for security and observability, data pipelines, helm chart development, and Kubernetes controllers. It’s very flexible and powerful for a wide range of development.
- AYBABTME 2y ago
  Same, being able to depend on CRDs between resources would be very useful, since a lot of my Tilt usage is about making operators or working with operators. Happy to see new releases of Tilt even if the pace has slowed down. It's a very useful tool.
- simultsop 2y ago
  As far as I understand, this might be is the best tool for the guy who acquires a SaaS and have no clue how to develop/tweak stuff. Again still have no clue how you enable this or do you still have tilt in production. Marketing is not a big deal for tilt as far as I understand.
  - cirego 2y ago
    You bring up an interesting question -- I think Tilt works best for those that find themselves in an environment where product is delivered using a service-oriented architecture deployed to Kubernetes. It's also easy to get started within a small team in a big company. To your other point, Tilt is to development as ArgoCD is to deployment. Tilt enables on-demand, reproducible development environments that are sufficiently high-fidelity that you can often replace your shared and/or long-lived testing clusters. With Tilt, I test my application using the same Kubernetes specs / Kustomizations / Helm Charts that you use to deploy into production. When it comes time to deploy my application, I supply these same specs / kustomizations / charts to ArgoCD. Because I can reuse the specs for both testing and production, I enjoy far greater testability of my application, improving quality and time to market.

    Disagree. It’s the same enterprise architecture gibberish that creates the problem in the first place.
sigmonsays 2y ago
i don't get the value of a tool like this. Do we really struggle bringing up services as containers and applying kube configs? For my development of services that run in kube, I don't dev with kube, you shouldn't have to. I also use docker-compose for most dev env services. Perhaps i'm not developing the right kind of software. Whoever finds this type of tool useful, when would you use it?
- Szpadel 2y ago
  I never used tilt, but it looks very useful for anything that needs kube API to work, like some operator or something that needs to discover configuration from config maps. otherwise I think it's meant for systems where system that you need for testing is to big to work on your local machine.
  - cirego 2y ago
    Yes, Tilt really shines when you’re testing interactions with Kubernetes, such a APIs. But also things like your services’ ingress configuration and metrics scraping. By default, Tilt is actually intended for local development using kind, minikube or other similar tooling. It supports developing against a multi-node cluster but it requires extra configuration and slows down iteration time.
- Noumenon72 2y ago
  If you have sidecar containers that feed your regular containers, or you need to test a Dask KubeCluster, or deploy Helm charts, this kind of lets you work with the real lifecycle. Tilt is kinda better at watching for code changes in all your containers than docker-compose too, and has a nice UI to watch logs and see what succeeded or failed.
  - cirego 2y ago
    Tilt can also help validate things like: - Service discovery - Volume mounts - Ingress and Certificates - Metrics scraping and configuration - Dashboards It’s really quite powerful and replaces the need to mock things out with docker compose. If you’re deploying to Kubernetes, Tilt gives you the option to avoid “development-only” setups like docker compose.

Isn't this essentially dev containers?
- Kuraj 2y ago
  Yeah it would be really useful to have in the readme what kind of problems this solves that dev containers don't solve already
- cirego 2y ago
  My understanding is that dev containers are more about configuring your development environment with the right toolchains to build and run services. Tilt is a monitor process that builds and starts your services, with a hot-reload loop that rebuilds and restarts your services when the underlying code changes. The hot reload loop even works for statically compiled languages.

Been using tilt as a make alternative for years. Great tooling, even as just file watch + pythonic syntax for running tests, etc. Obvs the real magic is the live syncing patches into remote containers though
siliconc0w 2y ago
You're always trading off speed with fidelity. Usually, trying to maintain a local integration environment is going to become too slow and expensive. The problem isn't even necessarily Kubernetes, but as dependencies increase it just gets slower and slower to try and run a copy of the world locally. I like a fast svelte dev environment with something like docker-compose which might require some mocked out dependencies to keep things fast and then using Kubernetes for other environments once I have local tests passing.
- cirego 2y ago
  I think that's a fair point -- you're making a tradeoff. And the best part is that you don't need to choose one or the other. In my case, I find that I prefer having higher fidelity and simpler service code by using Tilt to avoid mocks. It's also nice for frontend development because, using a Kubernetes ingress, you can avoid the need for things like frontend proxies, CORS and other development-only setup.
- hdjrudni 2y ago
  You can always swap out some of those services for always-running prod or dev-in-the-cloud services. I have a big mix of setups for my projects. I like Vite+Bun (client+server) for smallish projects because the dev servers start instantly. But then I have to remind myself how to actually productionize it when it comes time for that, but it's not too hard. Then sometimes I need to bring in a database. I don't like running those locally, undockerized because now you're locked into one specific version and it just gets messy. So sometimes if I'm lazy I just connect to my prod database server and just create a separate dev DB on it if needed. Then I don't need to start and stop anything, I just connect. Easy. For a big complex app you can mix-and-match any of the above. Run the services that you need to iterate heavily on locally, and just farm out the rarely changing stuff to the cloud.

How does Tilt compare to “skaffold dev“? We use skaffold exactly for that purpose. To develop within a the cluster.
- turtlebits 2y ago
  Skaffold works but its DX is pretty poor. Too many knobs via yaml- tilt has just enough magic that it doesn't feel like a chore to setup local dev.
  - cirego 2y ago
    I've always appreciated that Tilt chose Starlark instead of YAML. Makes things so much cleaner!
    - tomjakubowski 2y ago
      Well, now you've really got me interested. Almost every case of a YAML eDSL would be better served by Starlark instead, in my Bazel-brained opinion.
      - cirego 2y ago
        I think Tilt Extensions highlights the combined power and composability that using Starlarks brings to Tilt: https://docs.tilt.dev/extensions.html https://docs.tilt.dev/extensions.html. Want to create a Kubernetes secret? It's as simple as: load('ext://secret', 'secret_yaml_generic') k8s_yaml(secret_yaml_generic(...)) Want to create that secret from Vault instead? load('ext://vault_client', 'vault_read_secret', 'vault_set_env_vars') vault_set_env_vars('https://localhost:8200','mytoken') my_foo = vault_read_secret('path/myfoo', 'value') my_bar = vault_read_secret('path/mybar', 'foobar')
- eats_indigo 2y ago
  Migrated from Skaffold to Tilt at my last co, found it was much more easier to configure granular rebuild rules, which lead to faster dev loop cycles
philip1209 2y ago
If you want to see Tilt in action, our Chroma open-source repo uses it to run the distributed version of the database for development and ci. It's pretty cool - just clone then run `tilt up` and it's working: https://github.com/chroma-core/chroma https://github.com/chroma-core/chroma
- cirego 2y ago
  Thank you for sharing this! I think your Tiltfile just showed me how to solve something that's been bugging me for a while! I see that you also have docker-compose files -- are those for different tasks or for developer preference? I'm also curious to understand why you have different build scripts for CI (`buildx`) vs local (regular docker build)? In our team, we use the same build processes for both.
eats_indigo 2y ago
Love tilt, have found it much more difficult to set up in a docker-compose environment than a cloud native / minikube context
xyst 2y ago
I don’t think my problem has ever been with setting up a local environment. Single cluster deployments are very easy. My problem is that these services we manage in production are deployed across multiple regions (or k8s clusters). Debugging _distributed_ applications is the issue.
francescobianco 2y ago
Why do not use well organized Makefile instead of invent new junk. Is it a product placement?
- haolez 2y ago
  Makefiles are bad with state that is not represented as files, right? I remember that I had to create "stamp" files with hashes and things like that to overcome this limitation. There is also .PHONY, but that would make the rule to always be triggered. Maybe I'm misremembering, it's been a long time :)
- xyzzy_plugh 2y ago
  Makefiles are for building artifacts. They are wholly inadequate at orchestrating environments and task pipelines. Can you do it? Sure, but somewhere someone is going to be suffering.
- DonHopkins 2y ago
  Better yet, use a well organized "rm -rf" command!

hamandcheese 2y ago
I still think "dev environments" really ought to be running tests directly with your languages native tool. e.g. `cargo test`, `bundle exec rspec`, etc. If you make me run a VM that runs Kubernetes that runs a docker container that runs the tests, I will be very, very upset. Doing this properly and reliably can still be a lot of work, possibly more work if not relying on Docker is a design goal (which must be if you want to run natively on macOS). There seem to be a lot of tools in this space. I wish they wouldn't call themselves tools for "dev environments" when they are really more like tools for "deploying an app to your local machine", which is rather different.
- OptionOfT 2y ago
  Not to mention the developer experience is usually sub-par. I firmly believe that the primary way of interacting with my tests should be the ability to run them one by one from the IDE, and running the code should be run / attach with breakpoints.
  - michaelmior 2y ago
    It takes some work, but it's entirely possible to both use Docker and run individual tests with breakpoints (in a Docker container) in your IDE. For example, you can attach VS Code to a running container.
    - elktown 2y ago
      Yes, but it creates a restrictive and fragile happy-path when the aim imo should be closer to a lab/woodshop where you can take it apart however you like and need for the moment.
  - jbverschoor 2y ago
    Shell containers under code are unbearably laggy and crappy. I simple have a container for each project using my own container-shell I run my bundles / whatever. Have all the tooling and can use VSCode to attach via ssh (I use orbstack, so I get project hostnames for free) It’s the best workflow for me.
