GnuCash is a powerful open-source application for managing personal and business finances, supporting double-entry accounting, multi-currency, and tax reporting. However, its traditional use on local machines limits accessibility and collaboration. For distributed teams and remote work, a centralized, scalable platform is essential. Kubernetes enables deploying GnuCash in the cloud, providing browser-based access, automatic scaling, and centralized data storage. This guide will walk you through setting up GnuCash in Kubernetes, transforming it into a modern financial accounting tool.
Creating or Downloading Containers
Option 1 - Pre-built Image
The image includes VNC for browser-based access.
# Pull official image with web access support
docker pull jlesage/gnucash
# Test run to verify
docker run -d --name gnucash-test -p 5800:5800 jlesage/gnucash
Option 2 - Custom Image
A custom image allows environment customization.
Create `Dockerfile`:
FROM alpine:3.17
# Install GnuCash and dependencies for web access
RUN apk add --no-cache gnucash dbus-x11 xvfb-run websockify x11vnc fluxbox
# Set up user
RUN adduser -D -u 1000 gnucash
# Startup script
COPY startapp.sh /startapp.sh
RUN chmod +x /startapp.sh
USER gnucash
WORKDIR /data
EXPOSE 5800
ENTRYPOINT ["/startapp.sh"]
Create `startapp.sh`:
#!/bin/sh
xvfb-run --server-args="-screen 0 1920x1080x24" \
dbus-launch --exit-with-session \
fluxbox &
websockify --web /usr/share/novnc 6080 localhost:5900 &
x11vnc -display :99 -forever -passwd "${X11VNC_PASSWORD:-secret}" &
gnucash "$@"
3. Build the image:
docker build -t my-gnucash:latest .Deployment in Kubernetes
Architecture:
Step 1 - Persistent Volume Claim
PVC stores GnuCash data.
`gnucash-pvc.yaml`:
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: gnucash-data
namespace: finance
spec:
accessModes:
- ReadWriteOnce
storageClassName: ssd
resources:
requests:
storage: 20Gi
Step 2 - Deployment
Deploys GnuCash with persistent storage.
gnucash-deployment.yaml:
apiVersion: apps/v1
kind: Deployment
metadata:
name: gnucash
namespace: finance
spec:
replicas: 1
selector:
matchLabels:
app: gnucash
template:
metadata:
labels:
app: gnucash
spec:
securityContext:
runAsUser: 1000
fsGroup: 1000
containers:
- name: gnucash
image: jlesage/gnucash:latest
env:
- name: VNC_PASSWORD
valueFrom:
secretKeyRef:
name: gnucash-secrets
key: vnc-password
ports:
- containerPort: 5800
volumeMounts:
- name: gnucash-data
mountPath: /config
subPath: config
- name: gnucash-data
mountPath: /data
subPath: data
volumes:
- name: gnucash-data
persistentVolumeClaim:
claimName: gnucash-data
Step 3 - Service and Ingress
Enables access via a domain.
gnucash-service.yaml:
apiVersion: v1
kind: Service
metadata:
name: gnucash-service
namespace: finance
spec:
selector:
app: gnucash
ports:
- protocol: TCP
port: 5800
targetPort: 5800
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: gnucash-ingress
namespace: finance
spec:
tls:
- hosts:
- finances.example.com
secretName: gnucash-tls
rules:
- host: finances.example.com
http:
paths:
- path: /
pathType: Prefix
backend:
service:
name: gnucash-service
port:
number: 5800
Step 4 - PostgreSQL (Optional)
PostgreSQL for multi-user mode.
apiVersion: v1
kind: Service
metadata:
name: gnucash-db
namespace: finance
spec:
selector:
app: gnucash-db
ports:
- port: 5432
apiVersion: apps/v1
kind: Deployment
metadata:
name: gnucash-db
namespace: finance
spec:
selector:
matchLabels:
app: gnucash-db
template:
metadata:
labels:
app: gnucash-db
spec:
containers:
- name: postgres
image: postgres:15
env:
- name: POSTGRES_USER
value: gnucash
- name: POSTGRES_PASSWORD
valueFrom:
secretKeyRef:
name: gnucash-secrets
key: db-password
- name: POSTGRES_DB
value: gnucash_data
volumeMounts:
- name: db-data
mountPath: /var/lib/postgresql/data
volumes:
- name: db-data
persistentVolumeClaim:
claimName: gnucash-data
Step 5 - Secrets
kubectl create secret generic gnucash-secrets -n finance \
--from-literal=vnc-password='YourStrongPassword!' \
--from-literal=db-password='DBSecret123!'
Final Setup
Initial Access:
- Open `https://finances.example.com`.
- Enter the VNC password from Secrets.
- Create a new file: File → New File → SQLite3/PostgreSQL.
Automatic Backup:
Daily data backup
apiVersion: batch/v1
kind: CronJob
metadata:
name: gnucash-backup
namespace: finance
spec:
schedule: "0 3 * * *"
jobTemplate:
spec:
template:
spec:
containers:
- name: backup
image: alpine:3.18
command:
- /bin/sh
- -c
- |
apk add postgresql-client
PGPASSWORD=$DB_PASSWORD pg_dump -h gnucash-db -U gnucash gnucash_data > /backup/gnucash-$(date +%F).sql
gzip /backup/gnucash-*.sql
env:
- name: DB_PASSWORD
valueFrom:
secretKeyRef:
name: gnucash-secrets
key: db-password
volumeMounts:
- name: backup-volume
mountPath: /backup
volumes:
- name: backup-volume
persistentVolumeClaim:
claimName: gnucash-data
