Guide

1. Clone the repository:

   $ git clone https://github.com/int-i/integer.git

2. Build the source:

   $ cargo build

3. Run PostgreSQL:

   $ docker-compose -f docker-compose.db.yml up -d

Deploy

Requirement

• Docker
• db/password.txt - the DB password file
• cert.pem - the server certificate
• privkey.pem - the private key for the certificate
• chain.pem - (Option) the intermediate certificate

Guide

1. Build the Docker image:

   $ docker build -t integer_api .

   or, use Alpine-based image:

   $ docker build -f Dockerfile.alpine -t integer_api:alpine .

   Note: If you use Alpine-based image on aarch64-unknown-linux-musl, install libc6-compat on final stage of Dockerfile.

   RUN apk add --no-cache libc6-compat

2. Create the Docker secrets:

   $ docker secret create postgres_password db/password.txt
   $ cat cert.pem chain.pem privkey.pem | docker secret create site.pem -

   • postgres_password
   • site.pem

3. Deploy the application to Docker Swarm:

   $ docker swarm init
   $ docker stack deploy -c docker-compose.yml inti
