snippetbox

Snippetbox from Let' Go

Developing snippetbox example application following along "Let's Go" book from Alex Edwards

Generate TLS certificate

To generate the certificate to use for development, run the following command inside TLS folder:

go run /usr/lib/go/src/crypto/tls/generate_cert.go --rsa-bits=2048 --host=localhost

Run the application

Since we are going to run the database in a container, we need to create a network for the application and the database to communicate.

dk network create snippetbox

Run the database in a container with the following command:

dk run --rm -d \
    --name snippetbox-mysql \
    -e MYSQL_ROOT_PASSWORD=secret \
    -e MYSQL_DATABASE=snippetbox \
    -p 3306:3306 \
    --user 1000:1000 \
    --network snippetbox \
    -v $PWD/db-init.sql:/docker-entrypoint-initdb.d/db-init.sql \
    -v $PWD/data:/var/lib/mysql \
    mysql:8.3

Then we can run the application with the following command:

dk run -it --rm \
    --network snippetbox \
    -w $PWD -v $PWD:$PWD \
    -p 4000:4000 \
