# PISCAL Docker Build Guide
This guide explains how to build and run PISCAL Docker images.
## Prerequisites
- Docker installed and running
- Git (for version tagging)
- PowerShell (Windows) or Bash (Linux/Mac)
## Building the Image
**Windows (PowerShell):**
```powershell
.\build-docker.ps1
```
**Linux/Mac (Bash):**
```bash
./build-docker.sh
```
The build script automatically creates a versioned image with:
- `piscal:YYYYMMDD-gitsha` (e.g., `piscal:20260316-216cd3f`)
- `piscal:latest`
- `piscal:dev`
## Default Credentials
The image is built with default credentials:
- **Username:** `piscaladmin`
- **Password:** `piscaladmin`
- **Storage Path:** `/home/piscaladmin/LeafWeb_storage`
**Security Note:** Change the password after deployment for production use. You can change it by:
- SSHing into the container and running: `passwd piscaladmin`
- Or rebuilding with custom credentials using Docker build arguments (see Advanced section)
## Running the Container
```bash
# Start container
docker run -d -p 2222:22 --name piscal-server piscal:latest
# SSH into container
ssh -p 2222 piscaladmin@localhost
# Password: piscaladmin
# Stop and remove
docker stop piscal-server
docker rm piscal-server
```
## Container Configuration
### Build Arguments
The Dockerfile accepts these build arguments if you need to customize:
| Argument | Default | Description |
|----------|---------|-------------|
| `SSH_USERNAME` | `piscaladmin` | SSH username for container access |
| `SSH_PASSWORD` | `piscaladmin` | SSH password for container access |
| `SSH_GROUP` | `piscaladmin` | Primary group for SSH user |
| `STORAGE_PATH` | `/home/piscaladmin/LeafWeb_storage` | Storage directory for PISCAL data |
| `PISCAL_EXECUTABLE` | `/srv/piscal` | Path to PISCAL executable |
### Storage Directory Structure
The storage directory is automatically created with:
```
/home/piscaladmin/LeafWeb_storage/
├── input/ # Input files for processing
└── output/ # Results from PISCAL processing
```
### Port Mapping
- Container exposes port `22` for SSH
- Map to host port as needed: `-p <host_port>:22`
- Default examples use port `2222` to avoid conflicts with host SSH
## Advanced Usage
### Custom Credentials at Build Time
If you need different credentials, use Docker build arguments:
```bash
docker build \
--build-arg SSH_USERNAME=customuser \
--build-arg SSH_PASSWORD=custompass \
-t piscal:custom \
.
```
### Custom Storage Path
```bash
docker build \
--build-arg STORAGE_PATH=/data/piscal \
-t piscal:custom \
.
```
### Mounting External Storage
Mount a host directory for persistent storage:
```bash
docker run -d -p 2222:22 \
-v /path/on/host:/home/piscaladmin/LeafWeb_storage \
--name piscal-server \
piscal:latest
```
## Troubleshooting
### Build Issues
**Problem:** Docker build fails with "permission denied"
```bash
# Solution: Ensure Docker daemon is running
docker ps
```
**Problem:** Git not found during build
```bash
# Solution: Install git or build without versioning
docker build -t piscal:latest .
```
### Runtime Issues
**Problem:** Cannot SSH into container
```bash
# Check if container is running
docker ps
# Check container logs
docker logs piscal-server
# Verify SSH service
docker exec piscal-server service ssh status
```
**Problem:** Storage directory permission errors
```bash
# Verify ownership inside container
docker exec piscal-server ls -la /home/piscaladmin/LeafWeb_storage
```
**Problem:** Port conflict on 2222
```bash
# Use a different port
docker run -d -p 2223:22 --name piscal-server piscal:latest
ssh -p 2223 piscaladmin@localhost
```
## Version Management
### Listing Images
```bash
docker images | grep piscal
```
### Removing Old Images
```bash
# Remove specific version
docker rmi piscal:20260316-216cd3f
# Remove all except latest
docker images | grep piscal | grep -v latest | awk '{print $3}' | xargs docker rmi
```
## Security Best Practices
### 1. Change Default Password
After deploying, always change the default password:
```bash
# SSH into container
ssh -p 2222 piscaladmin@localhost
# Change password
passwd piscaladmin
```
### 2. Use SSH Keys
For better security, disable password authentication and use SSH keys:
```bash
# Copy your public key to the container
ssh-copy-id -p 2222 piscaladmin@localhost
# Disable password authentication (optional)
docker exec piscal-server sed -i 's/PasswordAuthentication yes/PasswordAuthentication no/' /etc/ssh/sshd_config
docker exec piscal-server service ssh restart
```
### 3. Firewall Rules
Restrict SSH access with firewall rules:
```bash
# Example: Allow only from specific IP
iptables -A INPUT -p tcp -s 192.168.1.100 --dport 2222 -j ACCEPT
iptables -A INPUT -p tcp --dport 2222 -j DROP
```
### 4. Environment Variables for Secrets
Store credentials as environment variables instead of hardcoding:
```bash
export PISCAL_USER="piscaladmin"
export PISCAL_PASS="secure_password"
docker build \
--build-arg SSH_USERNAME="$PISCAL_USER" \
--build-arg SSH_PASSWORD="$PISCAL_PASS" \
-t piscal:latest .
```
## Integration with CI/CD
### Example: GitHub Actions
```yaml
name: Build PISCAL Docker Image
on:
push:
branches: [main]
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v2
- name: Build Docker image
run: ./build-docker.sh
- name: Push to registry
run: |
docker tag piscal:latest myregistry/piscal:latest
docker push myregistry/piscal:latest
```
### Example: Jenkins
```groovy
pipeline {
agent any
stages {
stage('Build') {
steps {
sh './build-docker.sh'
}
}
stage('Deploy') {
steps {
sh 'docker tag piscal:latest myregistry/piscal:latest'
sh 'docker push myregistry/piscal:latest'
}
}
}
}
```

# PISCAL
PISCAL is a Fortran-based photosynthesis calculation tool for analyzing leaf-level gas exchange data. It supports C3, C4, and CAM photosynthetic pathways and provides parameter optimization for photosynthesis models.
## Quick Start with Docker
### Build the Docker Image
**Windows (PowerShell):**
```powershell
.\build-docker.ps1
```
**Linux/Mac (Bash):**
```bash
./build-docker.sh
```
### Run the Container
```bash
# Start container
docker run -d -p 2222:22 --name piscal-server piscal:latest
# SSH into container
ssh -p 2222 piscaladmin@localhost
# Password: piscaladmin
```
### Full Docker Documentation
See [README-Docker.md](README-Docker.md) for complete Docker build and deployment documentation, including:
- Container configuration
- Security best practices
- Troubleshooting
- CI/CD integration examples

└── README.txt # Manager scripts documentation
```
## Building from Source (Non-Docker)
PISCAL is written in Fortran and requires:
- `gfortran` (GNU Fortran compiler)
- `make`
- `xutils-dev`
To build manually:
```bash
cd leafres/testrun
make clean
make
```
The compiled executable will be located at `leafres/testrun/piscal`.
## Photosynthetic Pathway Support
PISCAL supports three photosynthetic pathway types:
- **C3_photosynthesis_leafweb** - C3 pathway (default)
- **C4_photosynthesis_leafweb** - C4 pathway
- **CAM_photosynthesis_leafweb** - CAM pathway
Specify the pathway type in the `piscal.cfg` configuration file.
## Input and Output
### Input Files
Place leaf gas exchange data files (CSV format) in the `input/` directory. See `piscal-manager/README.txt` for input file format details.
### Output Structure
PISCAL generates organized output in the following structure:
```
output/
├── clninput/ # Cleaned input data
└── fitresult/ # Optimization results
├── touser/ # User-facing results
│ ├── cntrlbestparameters.csv
│ ├── errormessage
│ └── warningmessage
└── nottouser/ # Internal/storage results
```
## Usage with piscal-manager Scripts
The container includes management scripts for job orchestration:
```bash
# Start a job
./piscal_manager.sh -d /path/to/workdir -s -p C3_photosynthesis_leafweb
# Check job status
./piscal_manager.sh -d /path/to/workdir
# Cleanup completed job
./piscal_manager.sh -d /path/to/workdir -c
```
See `piscal-manager/README.txt` for detailed script usage.
## Version History
Images are automatically tagged with:
- `piscal:YYYYMMDD-gitsha` - Date and commit-based version
- `piscal:latest` - Latest build
- `piscal:dev` - Development alias
## Security Notes
**Default Credentials:**
- Username: `piscaladmin`
- Password: `piscaladmin`
**Important:** Always change the default password after deployment:
```bash
ssh -p 2222 piscaladmin@localhost
passwd piscaladmin
```
See [README-Docker.md](README-Docker.md) for comprehensive security best practices.
