+# Covid 19 App
+
+Covid 19 app from `https://github.com/KevRunAmok/Covid19app` & dockerized by me to build both the app and the dependancy mysql container.
+>
+Clone that repo and copy the relevant files into the same directory as docker-compose.yml before moving on.
+
+*I'd highly recommend calling the image you create "kr/covidapp" insead of "kr/covid_whitney", that's an old name.*
+
+A few inital setup steps need to be taken if building the container from scratch. (see below)
+
+Also make sure that the `./schema` folder is created with sql to create the database and populate data.
+
+Note: If mysql can't start due to `Another process with pid 30 is using unix socket file`, this is likely because the socket file was locked when the container was last shut down. It persists to `/data/covid19/mysql.sock.lock` so removing this should fix the issue.
+
+### Build Image With Docker
+
+`docker build --tag="kr/covidapp" .`
+
+### Start with Docker-Compose
+
+Creates the mysql container, the covid container, and a shared network they communicate on.
+
+`docker-compose up -d`
+
+### Start with Plain Docker (Just the Covid App)
+
+Build the image with:
+
+`docker build --tag="kr/covidapp" .`
+
+Run the image with: 
+
+`docker run -d --name="covidapp" --network=mysql-network --restart=always -p 1337:1337 kr/covidapp`
+
+Note: this requires the mysql-network. If not created already create it with:
+
+`docker network create mysql-network`
+
+## Container Setup Steps
+
+1. Run the container(s) with docker-compose. Watch logs for mysql and wait till it's ready to aaccept connections.
+2. Create a user who can query the tables.
+- `docker exec -it mysql_covidapp mysql -uroot -proot`
+- `select * from mysql.user;`/`select Host, User from mysql.user;`
+- `CREATE USER 'kr_covid'@'%' IDENTIFIED BY 'kr_covid';`
+- `ALTER USER 'kr_covid'@'%' IDENTIFIED WITH mysql_native_password BY 'covid123';`
+- `GRANT ALL ON sql_covid19.* to 'kr_covid'@'%';`
+- After adding this user you can exec onto the container and run mysql from there.
+3. Import any data. (Note this step must be done each time the databases is wiped - aka when the persistant folder /data/covid19/mysql is deleted.)
+If you specified it in `./schema` it'll also be copied into `/docker-entrypoint-initdb.d/`
+
