Set Up FlowiseAI on Ubuntu 24.04 with Docker

Set Up FlowiseAI on Ubuntu 24.04 with Docker

FlowiseAI is a visual builder for AI workflows and agents, with a browser-based canvas for chaining models, tools, memory, and integrations without writing every orchestration step by hand. It is a strong fit when you want a self-hosted interface for prototyping AI pipelines on infrastructure you control.

In this guide, we restore a fresh Ubuntu 24.04.1 LTS server on Shape.Host, verify the current FlowiseAI stable release from the official project, install Docker Engine and Docker Compose from Docker’s official Ubuntu repository, deploy FlowiseAI 3.1.1 in a localhost-only container, and validate the setup screen safely over an SSH tunnel.

Application	FlowiseAI
Application version	3.1.1
Operating system	Ubuntu 24.04.1 LTS
Container runtime	Docker Engine 29.3.1 with Docker Compose 5.1.1
Supporting tools	Git 2.43.0 and OpenSSL 3.0.13
Access pattern	FlowiseAI bound to 127.0.0.1:3000 with browser access through an SSH tunnel
Validated on	Live Shape.Host Ubuntu 24.04.1 server

Why Use FlowiseAI on Ubuntu 24.04?

• FlowiseAI gives you a visual workspace for building and testing AI flows without writing a full custom frontend.
• Ubuntu 24.04.1 LTS provides a current and stable base for containerized apps.
• Docker keeps the deployment easy to reproduce and update.
• A localhost-only bind keeps the FlowiseAI editor off the public interface until you intentionally add a reverse proxy later.

Before You Begin

Make sure you have the following before you start:

• A fresh Ubuntu 24.04 server
• Root or sudo access
• An SSH key that can log in to the server
• A local workstation where you can open an SSH tunnel to the server

1. Verify the Ubuntu 24.04 Release

Start by confirming that the rebuilt server is actually running Ubuntu 24.04.1 LTS.

cat /etc/os-release

2. Install Docker Engine, Docker Compose, and Base Tools

FlowiseAI has an official Docker path, so the clean Ubuntu route is Docker’s official APT repository rather than relying on an older distro-packaged container stack.

apt-get update
apt-get install -y ca-certificates curl git openssl
install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
chmod a+r /etc/apt/keyrings/docker.asc

cat > /etc/apt/sources.list.d/docker.list <<EOF
deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
  $(. /etc/os-release && echo "${UBUNTU_CODENAME:-$VERSION_CODENAME}") stable
EOF

apt-get update
apt-get install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

systemctl enable --now docker

docker --version
docker compose version
git --version
ufw status || true

On the validated Ubuntu 24.04.1 server, this installed Docker Engine 29.3.1, Docker Compose 5.1.1, and Git 2.43.0.

3. Create the FlowiseAI Configuration

The official Docker image expects its persistent data to live under /root/.flowise inside the container. A small environment file plus a bind-mounted data directory is enough for a clean single-server deployment.

mkdir -p /opt/flowise/flowise-data
cd /opt/flowise

cat > .env <<'EOF'
PORT=3000
DATABASE_PATH=/root/.flowise
LOG_PATH=/root/.flowise/logs
SECRETKEY_PATH=/root/.flowise
BLOB_STORAGE_PATH=/root/.flowise/storage
EOF

cat > compose.yaml <<'EOF'
services:
  flowise:
    image: flowiseai/flowise:3.1.1
    container_name: flowise
    restart: unless-stopped
    env_file:
      - .env
    ports:
      - 127.0.0.1:3000:3000
    volumes:
      - ./flowise-data:/root/.flowise
EOF

grep '^PORT=' .env
grep '^DATABASE_PATH=' .env
grep 'image:' compose.yaml
grep '127.0.0.1:3000:3000' compose.yaml
docker compose config --services

This keeps FlowiseAI on localhost, persists its database and generated assets on the host, and pins the current stable image instead of following the moving latest tag in production.

4. Start FlowiseAI

With the configuration in place, pull the image and start the FlowiseAI container.

4.1 Launch the Container

cd /opt/flowise
docker compose pull
docker compose up -d
sleep 30
docker compose ps

On the validated server, Docker pulled flowiseai/flowise:3.1.1, created the container, and brought the service up successfully.

4.2 Validate the Local HTTP Response

docker compose ps
docker compose images
curl -I http://127.0.0.1:3000

The live deployment returned HTTP/1.1 200 OK from the local FlowiseAI route, which is the expected result before you open the editor through an SSH tunnel.

5. Open the FlowiseAI UI Through an SSH Tunnel

This installation keeps FlowiseAI on localhost instead of exposing the editor directly to the public network. Create an SSH tunnel from your local machine, then open the forwarded port in your browser.

ssh -L 13000:127.0.0.1:3000 root@YOUR_SERVER_IP

After the tunnel is open, browse to:

http://127.0.0.1:13000

On the live server, the initial FlowiseAI setup screen loaded correctly through the tunnel and was ready for the first administrator account.

6. Run Final Server-Side Checks

Before you stop, confirm that the container is still healthy, the port is bound only to localhost, and the local HTTP response remains available.

cd /opt/flowise
docker compose ps
docker compose images
ss -lntp | grep ':3000'
curl -I http://127.0.0.1:3000

On the validated deployment, the final check showed FlowiseAI listening only on 127.0.0.1:3000 and still returning 200 OK locally.

Conclusion

You now have FlowiseAI on Ubuntu 24.04 running in Docker with persistent local data and a safer localhost-only access pattern. From here, you can finish the first-account setup, connect your preferred model providers, and only add a public reverse proxy later if you decide you need browser access without SSH tunneling.
