Docker × Laravel HTTPS (SSL) communication in local environment

There is a request for HTTPS communication even in the local environment, and I just recently had the opportunity to do it at work, so I would like to summarize it in Qiita as well.

Laravel environment construction

$ git clone [email protected]:ucan-lab/docker-laravel.git
$ cd docker-laravel
$ make create-project

Certificate authority, key preparation

Installation of mkcert, nss

$ brew install mkcert nss

Creating a Local Certificate Authority (CA)

$ mkcert -install

Hide Chrome SSL warnings only on localhost. chrome: // flags/# allow-insecure-localhost Type in the address bar.

Change to DISABLED => ENABLED and restart your browser.

Creating private and public keys

Execute the command in the docker-laravel directory root.

$ mkcert -cert-file ./infra/docker/nginx/localhost.pem -key-file ./infra/docker/nginx/localhost-key.pem localhost

Docker code rewriting


Change the public port from 80 to 443. For HTTPS, 443 is generally used as the well-known port number.


      - ${WEB_PORT:-443}:443


Add the following code.


server {
    # listen 80;
    listen 443 ssl;
    server_name localhost;
    ssl_certificate /etc/nginx/conf.d/localhost.pem;
    ssl_certificate_key /etc/nginx/conf.d/localhost-key.pem;

    # ...abridgement


Add the following code.


COPY ./*.pem /etc/nginx/conf.d/

--The private key and public key are copied.

Docker image creation, container regeneration

Execute the command in the docker-laravel directory root.

$ docker-compose build web
$ make restart

It is ok if the SSL certificate is activated like this.
