Sarathy

• general purpose toolchain to build cli, web & container apps using docker & k8s
• low-code, no-code
• minikube in docker, k3s in docker
• various modern CLI & CNCF tools

"one with a chariot"

Usage : only pre-req is Docker Desktop installed/available on host OS(win/mac/*nix)

# Run minikube in docker
curl -sfL https://savyasachi9.github.io/sarathy/platform/sarathy.sh | bash -s -- minikube run

# Run k3s in docker
curl -sfL https://savyasachi9.github.io/sarathy/platform/sarathy.sh | bash -s -- k3s run

# Or just run docker in docker
curl -sfL https://savyasachi9.github.io/sarathy/platform/sarathy.sh | bash -s -- latest run

# Visit webtty/gotty with bash in browser (not available for arm64 yet)
http://localhost:9090

support for amd64 & arm64 (apple m1, raspberry pi etc)

all the tools in container image are installed for user 'docker'

minikube/k3s images come pre-installed with mysql8.0 and redis6.2 using helm charts

Programming Languages container

• c/c++, gcc 9, gdb
• golang1.17, dlv
• php8.1, xdebug
• python3.8, pip3

# You can either run 'sarathy' container to use 'langtools/plt' container or run it like
curl -sfL https://savyasachi9.github.io/sarathy/platform/sarathy.sh | bash -s -- plt run

# Visit code-server/vscode IDE in browser
http://localhost:9091/?folder=/src/

# Visit webtty/gotty with bash in browser (not available for arm64 yet)
http://localhost:9092

# Connect to langtools/plt container
docker exec -it sarathy-plt /bin/bash

# Connect to langtools container thru sarathy-minikube container
docker exec -it --user docker sarathy-minikube /bin/bash -c "docker exec -it langtools bash"

above languages are pre-installed with debug extensions, use key 'F5' to run debugger in IDE

Target Audience

• Students (Grade 6+ ---> PHD)
• Devs, Tinkerers
• Enterprise, Schools, Colleges, Programming/Coding Bootcamps

Project Goals

• Help one stay upto date with modern tooling to solve problems & keep experimenting forever.
• Bridge the ever growing gap between enterpeise & academia where academia is behind what's used in enterprise.
• Lower the entry bar for to get started with building cli/web/container applications.
• Create a bridge between DEV & DEVOPS along with DEV teams such that they all speak the same language for apps & infra.
• 10+ users by EOY 2022, 100+ by EOY 2023, 1000+ by EOY 2024 ...

Roadmap : Q1/Q2 2022 / finish MVP with stable version

• build toolchain with cutting edge tools as Dockerimage which has capability to run k8s clusters within a container
• support diff programming languages with code-server IDE to build apps
• publish @ github & dockerhub

Roadmap : Q3/Q4

• add examples/tutorials on how can one use sarathy to build cli/containers/k8s/web apps
• add examples for diff ci/cd tools (skaffold, tilt, devspace, helm, docker, simple app cmds) using Taskfile
• improve upon toolchain & finish open TODOs
• demos, feedback, improvise & get more users !
• publish sarathy.dev

Roadmap : Q1 2023 & beyond

• TBD

Security : The good, bad & ugly to look out for

• Never commit ssh keys & other aws, azure, gcloud keys as part of the docker image (wipe things out from the live image of such sort if there's any).
• Scan Sarathy images for vulnerabilities and keep them to minimal.
• Make sure all the open source tools being added in Sarathy's toolchain are properly vetted/examined.
• For all the open source tools we are using, disable telementary or any other kind of tracking to collect user data/stats etc.
• Use wireguard etc to keep an eye on Sarathy's network activity to ensure no tools are tracking

Publish, Market, Onboard & Support Users

• to friends and devs for feedback
• at places where folks are looking for getting up & running with k8s locally
• in various online/offline forums wherever people are in need for such a toolchain or can benefit from it
• setup discord channel or something similar to support users issues

Thank-yous, Credits & References

• Many thanks to all the folks whose open source tools/tutorials are stitched together for building this toolchain.
• Much appreciate the folks who are helping build 'sarathy' with their valuable feedback & immense contributions.
