Build and test

Dex(Ops)Experience for deployments and other ops operations made easy.

Make docker compose for default nginx:

cat > docker-compose.yaml << EOL
version: "3.7"
services:
  nginx:
    image: nginx:latest
    ports:
    - "80:80"
EOL

Let's call build now:

opday docker build

This tool requires local installation of another tools and their availability in the shell: docker, ssh, rsync.

The idea

This tool prioritizes simplicity and imperativeness over scaling and decorativeness. It provides a simple yet flexible way to maintain basic Ops operations and automates its own infrastructure. There are plenty amount of deploy.sh scripts we might write manually or tools like umputun/spot, Kamal or Ansible. Usage of some of them might be overkill, but also I don't want to force people to learn one more DSL for this obvious deployment stuff. Hence, the main features are based on docker and docker compose.

  • Allocation of resources on virtual private and dedicated servers
  • Multiple providers support (docker, databases, monitoring, S3, and other storages)
  • Reverse-proxies configuration
  • Monitoring with metrics and alerts
  • Logs collection tools
  • Backups and checking for backups infra
  • Secrets management
  • Support of existing APIs
  • Migration tools to lambdas or Kubernetes

Scope of applying this tool:

  • Product is not Kubernetes ready. Kubernetes for monolithic or citadel-like applications brings more complexity than solving problems in the early stages.
  • Less than 100 virtual machines for service. More hosts might become an issue for straightforward push architecture.
  • Up to 100 daily releases
  • Base-level infra with trivial sharding and replication for storage and databases. Everything above might be more suitable for custom or cloud-managed services.

User guide

Getting started

Preparing host

For Ubuntu docker please follow: https://docs.docker.com/engine/install/ubuntu/

Dev

We use pre-commit.

pre-commit install
pre-commit

Linters and tools:

rustup component add clippy
cargo binstall cargo-watch

Random notes:

# I have some questions to global rust and git hooks work together.
# So we link cargo to repository root to have the same code running
# with `make`, CI and git hooks.
ln -s `which cargo`

# Support RUST_LOG environment
RUST_LOG=debug cargo run

# Run tests with watch on change
make testw
