+We're using Ubuntu Linux. You'll have to make the required tweaks for your preferred Linux Distro. Find the list of support operating systems [here](/docs/node/requirements#server).
+:::
+
+```sh
+sudo apt update
+```
+
+Next, install the required packages to let apt use packages over HTTPS:
+
+```sh
+sudo apt install \
+  apt-transport-https \
+  ca-certificates \
+  software-properties-common
+```
+
+Add the GPG key for the official Docker repository to your system:
+
+```sh
+curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
+```
+
+Add the Docker repository to apt sources and update the package database with the Docker packages from the new added repository:
+
+```sh
+sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu jammy stable"
+```
+
+Set to install from the Docker repo instead of the default Ubuntu repo:
+
+```sh
+apt-cache policy docker-ce
+```
+
+Finally, install Docker:
+
+```sh
+sudo apt install docker-ce
+```
+
+Once complete you should be able to run it via the CLI, as such:
+
+```sh
+docker -v
+```
+
+Here's the output (versions might differ a bit from the time of writing):
+
+```sh
+Docker version 24.0.6, build ed223bc
+```
+
+## Docker setup verification
+
+The following command's output will indicate if Docker's working correctly:
+
+```sh
+sudo docker run hello-world
+```
+
+You should get a "Hello from Docker!".
+
+## Create the Dockerfile
+
+```sh
+touch Dockerfile
+```
+Copy and paste to the Dockerfile the following content:
+
+```sh
+FROM rust:latest as builder
+ARG PROFILE=release
+WORKDIR /lightning
+
+RUN apt-get update
+RUN apt-get install -y \
+    build-essential \
+    cmake \
+    clang \
+    pkg-config \
+    libssl-dev \
+    gcc \
+    protobuf-compiler
+
+RUN --mount=type=cache,target=/usr/local/cargo/registry \
+    cargo install cargo-strip
+
+COPY . .
+ENV RUST_BACKTRACE=1
+
+RUN --mount=type=cache,target=/usr/local/cargo/registry \
+    --mount=type=cache,target=/lightning/target \
+    cargo build --profile $PROFILE --bin lightning-node \
+    && cargo strip \
+    && mv /lightning/target/release/lightning-node /lightning-node
+
+FROM ubuntu:latest
+
+RUN DEBIAN_FRONTEND=noninteractive apt-get update -yq && \
+  DEBIAN_FRONTEND=noninteractive apt-get install -yq \
+    libssl-dev \
+    ca-certificates
+
+# Get compiled binaries from builder's cargo install directory
+COPY --from=builder /lightning/target/release/lightning-node /usr/local/bin/lgtn
+
+ENTRYPOINT ["lgtn", "run"]
+```
+
+## Build the Docker image
+
+Build the image named as `lightning` from our Dockerfile:
+
+```sh
+sudo docker build -t lightning -f ./Dockerfile .
+```
+
+## Generate keys
+
+```sh
+sudo docker exec -it lightning-cli lgtn keys generate
+```
+
+## Docker Container
+
+```sh
+sudo docker run \
+  -p 4069:4069 \
+  -p 4200:4200 \
+  -p 6969:6969 \
+  -p 18000:18000 \
+  -p 18101:18101 \
+  -p 18102:18102 \
+  -v $HOME/.lightning/:/root/.lightning/:rw \
+  --name lightning-cli \
+  -it lightning
+```
+
+## View logs
+
+To view the logs of a Docker container in real time, use the following command:
+
+```sh
+sudo docker logs -f lightning-cli
+```
