Setup

Install steps are for Debian 9 (stretch)

1. Install docker-ce

   # stolen from https://docs.docker.com/install/linux/docker-ce/debian/
   sudo apt-get remove docker docker-engine docker.io containerd runc
   sudo apt-get update
   sudo apt-get install apt-transport-https ca-certificates curl gnupg2 software-properties-common
   curl -fsSL https://download.docker.com/linux/debian/gpg | sudo apt-key add -
   # verify the key's fingerprint
   # ----------
   sudo apt-key fingerprint 0EBFCD88
       pub   4096R/0EBFCD88 2017-02-22
       Key fingerprint = 9DC8 5822 9FC7 DD38 854A  E2D8 8D81 803C 0EBF CD88
       Docker Release (CE deb) <docker@docker.com>
       sub   4096R/F273FCD8 2017-02-22
       # ----------
   sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/debian $(lsb_release -cs) stable"
   sudo apt-get update
   sudo apt-get install docker-ce docker-ce-cli containerd.io
   

2. Install golang 1.11

   # stretch doesn't have the latest golang so we install backports
   sudo add-apt-repository "deb http://deb.debian.org/debian stretch-backports main"
   sudo apt-get update
   sudo apt-get -t stretch-backports install golang
   # set the gopath manually for the rest of the setup
   export GOPATH=${HOME}/go
   

3. Install migrate

   # this assumes you have ${GOPATH}/bin in your ${PATH}
   go get -u -d github.com/mattes/migrate/cli github.com/lib/pq
   go build -tags 'postgres' -o ${GOPATH}/bin/migrate github.com/mattes/migrate/cli
   
   

4. Clone repo and configure the settings

   mkdir -p ${GOPATH}/src/git.minhas.io/asara
   cd ${GOPATH}/src/git.minhas.io/asara
   git clone https://git.minhas.io/asara/sudoscientist-go-backend
   # iterate through the environment files in the settings directory and set them appropriately
   # make sure the extension is .env (db.env, secrets.env, website.env... etc.)
   

5. Configure docker postgres for testing

   # make sure your user is in the docker group
   sudo usermod -aG docker $(whoami)
   # make sure you have some postgres client installed
   sudo apt-get install postgres-client
   docker pull postgres
   docker run --name sudosci-db -e POSTGRES_PASWORD=${DB_ADMIN_PW} -d postgres # please set the db admin pw manually
   # Initalize the postgres DB
   cd ${GOPATH}/src/git.minhas.io/asara/sudoscientist
   for i in settings/*; do source $i; done
   export DB_HOST=$(docker inspect -f "{{ .NetworkSettings.IPAddress }}" sudosci-db)
   psql -d postgres -U postgres -h ${DB_HOST} << EOF
   CREATE DATABASE ${DB_NAME};
   CREATE USER ${DB_USER} WITH ENCRYPTED PASSWORD '${DB_PW}';
   GRANT ALL PRIVILEGES ON DATABASE ${DB_NAME} TO ${DB_USER};
   ALTER DATABASE ${DB_NAME} OWNER TO ${DB_USER};
   EOF
   

6. Run the application!

   cd ${GOPATH}/src/git.minhas.io/asara/sudoscientist-go-backend
   for i in settings/*; do source $i; done
   export DB_HOST=$(docker inspect -f "{{ .NetworkSettings.IPAddress }}" sudosci-db)
   PSQL_QUERY_STRING="postgres://${DB_USER}:${DB_PW}@${DB_HOST}:${DB_PORT}/${DB_NAME}?sslmode=${DB_SSL}"
   migrate -path migrations/ -database ${PSQL_QUERY_STRING} up
   go get
   go run main.go
