Show HN: OYS Bitnami Builder – Build your own Bitnami containers

2 hours ago 2

An interactive script to discover, build, and deploy Bitnami containers with multi-platform support and flexible output options.

🔍 Interactive Menu - Browse and select from all available Bitnami containers
🏗️ Multi-Platform Builds - Support for ARM64, AMD64, and other architectures
📦 Dual Output Modes - Push to registries OR create portable OCI archives
🤖 Automation Ready - Fully scriptable for CI/CD and cron jobs
🔐 Registry Flexibility - Works with Docker Hub, private registries, and local registries
⚡ Smart Caching - Sparse Git clones and intelligent rebuild detection

# Clone and make executable git clone <your-repo> chmod +x oys-bitnami-builder.sh # Interactive mode (default) ./oys-bitnami-builder.sh # Show help ./oys-bitnami-builder.sh help

I have designed and built this with Claude, so there may be bugs like any sofware and this is a first version.

Docker with buildx support
Git
Bash 4.0+

Optional (for archive mode)

Skopeo - Required for OCI archive creation
Buildah - Optional, enables multi-arch manifest archives
curl - For registry connectivity testing

macOS (Homebrew):

brew install docker git skopeo buildah

Ubuntu/Debian:

apt update && apt install -y docker.io git skopeo buildah curl

RHEL/CentOS:

yum install -y docker git skopeo buildah curl

1. Interactive Menu (Default)

Browse and select from all available Bitnami containers:

=== Available Bitnami Containers === Choose a container to build: 1) gitea 1/debian-12 (v1.21.5) 2) nginx 1.25/debian-12 (v1.25.3) 3) postgresql 15/debian-12 (v15.5.0) 4) redis 7.2/debian-12 (v7.2.4) ... Enter your choice (0-123):

# Build specific container REPO=gitea SUBDIR=bitnami/gitea/1/debian-12 ./oys-bitnami-builder.sh build # Non-interactive build INTERACTIVE=false REPO=nginx SUBDIR=bitnami/nginx/1.25/debian-12 ./oys-bitnami-builder.sh build

# Docker Hub ./oys-bitnami-builder.sh # Private registry REGISTRY=registry.company.com ./oys-bitnami-builder.sh # Local registry REGISTRY=localhost:5000 ./oys-bitnami-builder.sh

Output:

Multi-platform manifests in registry
Automatic platform detection and building
Registry authentication handling

Creates portable OCI archives using Skopeo, perfect for air-gapped environments.

Loading Archives with Skopeo

# Load to local Docker daemon skopeo copy oci-archive:tzahifadida-nginx-1.25.3.tar docker-daemon:nginx:1.25.3 # Load specific platform skopeo copy oci-archive:tzahifadida-nginx-1.25.3-linux-amd64.tar docker-daemon:nginx:1.25.3 # Deploy to another registry skopeo copy oci-archive:tzahifadida-nginx-1.25.3-linux-arm64.tar docker://prod-registry.com/nginx:1.25.3 # Copy between registries skopeo copy oci-archive:tzahifadida-nginx-1.25.3-multiarch.tar docker://registry.company.com/nginx:1.25.3

podman load < tzahifadida-nginx-1.25.3.tar

Multi-Registry Deployment

# Build once, deploy to multiple registries OUTPUT_MODE=archive PLATFORMS="linux/amd64,linux/arm64" ./oys-bitnami-builder.sh # Deploy to production skopeo copy oci-archive:tzahifadida-nginx-1.25.3-linux-amd64.tar docker://prod-registry.com/nginx:1.25.3-amd64 skopeo copy oci-archive:tzahifadida-nginx-1.25.3-linux-arm64.tar docker://prod-registry.com/nginx:1.25.3-arm64

Custom Namespace and Tagging

# Custom namespace for company builds NS=acme-corp REGISTRY=registry.acme.com ./oys-bitnami-builder.sh # Results in: registry.acme.com/acme-corp/nginx:1.25.3

# Quick local testing REGISTRY=localhost:5000 PLATFORMS=linux/amd64 ./oys-bitnami-builder.sh # Production multi-arch build REGISTRY=prod-registry.com PLATFORMS="linux/amd64,linux/arm64" FORCE_REBUILD=true ./oys-bitnami-builder.sh

1. "Missing dependency" errors

# Install missing tools brew install docker git skopeo # macOS apt install docker.io git skopeo # Ubuntu

2. "Cannot access registry" warnings

# Login to registry first docker login registry.company.com # Or skip authentication REGISTRY_AUTH=none ./oys-bitnami-builder.sh

3. "buildx builder not found"

# Create and use a buildx builder docker buildx create --name mbuilder --use docker buildx inspect --bootstrap

4. Archive mode fails

# Check if skopeo is installed which skopeo # Install skopeo brew install skopeo # macOS apt install skopeo # Ubuntu
