+# PHP 7.4 & Apache Dockerfile Example

+
+## Build Image
+
+Build the ***Docker Image*** without using ***cached*** versions of previous image build stages.
+
+**N.B.**
+
+This ***requires*** that the file be named `Dockerfile` and nothing else.
+
+```bash
+sudo docker build --target php-7-4-build --no-cache -t php-7-4-web-server .
+```
+
+### Create A Container
+
+This creates a named container and attaches it to the ***host network*** and may cause port conflict if the host machine is already listening on any exposed ports from the ***Docker Image*** being used.
+
+```bash
+sudo docker run -d --network host --name container-name php-7-4-web-server
+```
+
+**OR**
+
+This creates a named container and attaches it to the ***bridge network*** and allows for ***port forward mapping*** from the ***host*** to the ***Container***.  The ports are mapped **8080** on the ***Host*** machine to port **80** on the ***Container***
+
+```bash
+sudo docker run -d --network bridge --expose 8080:80 --name container-name php-7-4-web-server
+```
+
+### Start Container
+
+```bash
+sudo docker start php-7-4-web-server
+```
+
+### Stop Container
+
+```bash
+sudo docker stop php-7-4-web-server
+```
+
+## Docker Compose
+
+A `docker-compose` configuration file is included to simplify the build & deployment of the image.
+
+### Build - No Cache
+
+This is only necessary when completely rebuilding the image to make sure all parts are rebuilt[^compose_name_note].
+
+```bash
+sudo docker-compose build --no-cache php-7-4-web-server
+```
+
+### Build & Up
+
+This will try to use a local version or rebuild the image with current context.
+
+```bash
+sudo docker-compose up --build -d
+```
+
+## Connect To Container
+
+```bash
+sudo docker exec -it php-7-4-web-server /bin/bash
+```
+
+[^docker_pull_cmd_note]: Use `docker pull ewc2020/web:php-5.6-apache` to get a copy of the image.
+
+[^compose_name_note]: The `php-7-4-web-server` container name to build the image for.
