aws_drogon

Running drogon server on Amazon Linux (suitable for t2.micro free tier EC2 instances) while minimizing cost.

"Cross compile" by building your Drogon application on an Amazon Linux Docker image

Clone this repo for a modified Dockerfile built on the amazonlinux:latest

Setting up Docker container for compiling Drogon applications

git clone https://github.com/timulations/aws_drogon.git
cd aws_drogon

# build docker image
# here I used linux/amd64 for the t2.micro Amazon-Linux free tier EC2 instance, replace with your desired architecture
docker build -t amazonlinux_drogon_amd64:latest --platform linux/amd64 .

# run docker container from image
# replace HOST_PORT:CONTAINER_PORT with port mapping of desire for testing your
# drogon server
docker run -td -p HOST_PORT:CONTAINER_PORT amazonlinux_drogon_amd64 --platform linux/amd64

# find out the container name
docker ps

docker cp your/drogon/project/folder YOUR_CONTAINER_ID:/desired/location/in/container

Then simply build/compile your Drogon project inside the Docker container!

Transferring built server binary onto AWS EC2 instance

Once the compilation is complete you can just scp the binary directly to the EC2 instance for deployment, without wasting EC2 computation time/power and storage space for compiling the Drogon server binary. Save some money 💰

scp -i path/to/your/rsa/key.pem your/built/drogon/binary ec2-user@<address>.<geo>.compute.amazonaws.com:/desired/location/on/ec2/instance

Runtime dependencies

Drogon will depend on libjsoncpp.so at runtime. So you can either scp that as well into a location within $PATH on your EC2 instance, or build from scratch in there.

dnf install -y git
dnf install -y gcc
dnf install -y gcc-c++
dnf install -y cmake

git clone https://github.com/open-source-parsers/jsoncpp
df jsoncpp
mkdir build && cd build
cmake ..
make && make install
