Deploy Odoo on Oracle Cloud Free Tier: Complete Guide (2026)

Why Oracle Cloud for Odoo?

Oracle Cloud Infrastructure (OCI) offers the most generous free tier of any cloud provider. The Always Free tier includes ARM-based compute instances with up to 4 OCPUs (equivalent to 4 vCPUs) and 24GB RAM — resources that would cost $50-100 per month on other providers. For Odoo, this is enough to run a production instance serving 50-100 users at zero cost.

The catch: ARM (Ampere A1) instances require ARM-compatible software. Odoo runs perfectly on ARM with the official Docker image or native installation on Ubuntu ARM.

Oracle Cloud Always Free Resources

Step 1: Create Oracle Cloud Account

1. Go to cloud.oracle.com and sign up
2. You need a credit card for verification (you will not be charged for Always Free resources)
3. Select your home region (cannot be changed later)
4. Wait for account activation (usually instant)

Step 2: Create ARM Instance

1. Go to Compute → Instances → Create Instance
2. Name: odoo-server
3. Image: Ubuntu 24.04 (Canonical)
4. Shape: VM.Standard.A1.Flex (Ampere ARM)
5. OCPU count: 4, Memory: 24 GB
6. Boot volume: 100 GB
7. Add your SSH public key
8. Create

Note: ARM instances may show "Out of capacity" in popular regions. Try different availability domains, or try during off-peak hours. Persistence pays off.

Step 3: Configure Security Lists

Oracle Cloud blocks all ingress traffic by default. Open the required ports:

1. Go to Networking → Virtual Cloud Networks → your VCN → Security Lists
2. Add ingress rules for ports 80, 443, and 22 (SSH)

# Also open ports on the instance firewall
ssh ubuntu@YOUR_OCI_IP
sudo iptables -I INPUT 6 -m state --state NEW -p tcp --dport 80 -j ACCEPT
sudo iptables -I INPUT 6 -m state --state NEW -p tcp --dport 443 -j ACCEPT
sudo netfilter-persistent save

Step 4: Install Odoo

# Update system
sudo apt update && sudo apt upgrade -y

# Install PostgreSQL
sudo apt install -y postgresql
sudo -u postgres createuser --createdb odoo
sudo -u postgres psql -c "ALTER USER odoo WITH PASSWORD 'secure_pw';"

# Install Odoo dependencies
sudo apt install -y git python3-pip python3-dev python3-venv \
    libxml2-dev libxslt1-dev zlib1g-dev libsasl2-dev \
    libldap2-dev build-essential libssl-dev libffi-dev \
    libjpeg-dev libpq-dev npm

# Create Odoo user and clone
sudo adduser --system --home=/opt/odoo --group odoo
sudo su - odoo -s /bin/bash -c '
git clone https://github.com/odoo/odoo.git --depth 1 --branch 19.0 /opt/odoo/odoo
python3 -m venv /opt/odoo/venv
source /opt/odoo/venv/bin/activate
pip install --upgrade pip wheel
pip install -r /opt/odoo/odoo/requirements.txt
'

# wkhtmltopdf for ARM
sudo apt install -y wkhtmltopdf

Step 5: Configure and Start

# Create odoo.conf
sudo tee /etc/odoo.conf > /dev/null << 'EOF'
[options]
admin_passwd = your_master_password
db_host = localhost
db_port = 5432
db_user = odoo
db_password = secure_pw
addons_path = /opt/odoo/odoo/addons
data_dir = /opt/odoo/data
workers = 4
max_cron_threads = 1
limit_memory_hard = 2684354560
limit_memory_soft = 2147483648
limit_time_cpu = 600
limit_time_real = 1200
proxy_mode = True
EOF

# Create systemd service
sudo tee /etc/systemd/system/odoo.service > /dev/null << 'EOF'
[Unit]
Description=Odoo 19
After=postgresql.service

[Service]
Type=simple
User=odoo
ExecStart=/opt/odoo/venv/bin/python /opt/odoo/odoo/odoo-bin -c /etc/odoo.conf
Restart=on-failure

[Install]
WantedBy=multi-user.target
EOF

sudo systemctl daemon-reload
sudo systemctl enable odoo
sudo systemctl start odoo

Step 6: Nginx + SSL

sudo apt install -y nginx certbot python3-certbot-nginx

# Configure nginx
sudo tee /etc/nginx/sites-available/odoo > /dev/null << 'CONF'
upstream odoo {
    server 127.0.0.1:8069;
}
server {
    listen 80;
    server_name erp.yourdomain.com;
    
    location / {
        proxy_pass http://odoo;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}
CONF

sudo ln -s /etc/nginx/sites-available/odoo /etc/nginx/sites-enabled/
sudo nginx -t && sudo systemctl reload nginx
sudo certbot --nginx -d erp.yourdomain.com

ARM Performance for Odoo

Ampere A1 ARM processors deliver excellent per-core performance. Benchmarks show ARM Odoo performance within 5-10% of equivalent x86 instances, sometimes faster for multi-threaded workloads. The 4 OCPU / 24GB RAM configuration handles Odoo comfortably:

• 4 Odoo workers + 1 cron thread
• PostgreSQL with 4GB shared_buffers
• Comfortable headroom for nginx and system processes

Limitations of Free Tier

• No SLA (free resources can theoretically be reclaimed, though this is rare)
• ARM shape availability can be limited in popular regions
• No managed database in free tier (you run PostgreSQL yourself)
• Object storage limited to 20GB for backups

DeployMonkey + Oracle Cloud

DeployMonkey supports Oracle Cloud as a deployment target. Connect your OCI account and deploy Odoo instances on the free tier with automated configuration, monitoring, and backup management.
