What is Caddy
Caddy is an open source web server with automatic HTTPS.
We will use it to create a simple "api gateway".
Preparing sample services
Start sample services
docker container run -d -p 5000:5000 proclaim/crp-app1
docker container run -d -p 8800:8800 proclaim/crp-app2
Test services
curl http://localhost:5000/api/member
curl http://localhost:8800/api/food
Configuring local caddy
mkdir ~/api-gateway
cd ~/api-gateway
Obtain machine information
hostname
ziba-Aspire-A515-51G.adzubla.net
hostname -I
192.168.59.50
Create the SSL certificate for this machine
openssl req -nodes -new -x509 -keyout server.key -out server.cert \
-subj "/C=AU/ST=Some-State/L=City/O=Company Name/OU=Department/CN=ziba-Aspire-A515-51G.adzubla.net"
Create Caddyfile configuration
ziba-Aspire-A515-51G.adzubla.net {
tls /etc/server.cert /etc/server.key
proxy /api/member 192.168.59.50:5000
proxy /api/food 192.168.59.50:8800
}
Start caddy server
docker run -d \
-p 443:2015 \
-v $HOME/api-gateway/Caddyfile:/etc/Caddyfile \
-v $HOME/api-gateway/server.key:/etc/server.key \
-v $HOME/api-gateway/server.cert:/etc/server.cert \

Test https services through caddy
curl -k https://ziba-aspire-a515-51g.adzubla.net/api/member
curl -k https://ziba-aspire-a515-51g.adzubla.net/api/food
