Running a nodejs application with mysql database as microservices using docker

# getting started with docker-mysql-nodejs

3+
Running a nodejs application with mysql database as microservices using docker
4+
using microservice architecture
5+
6+
### our end goal
7+
8+
- Launch mysql server in a docker container.
9+
- Launch our simple node app in a separate container.
10+
- Link these two containers and test our integrated mysql-nodejs app.
11+
12+
### prerequisite
13+
14+
- must have docker set up and running on your system
15+
16+
### Launching mysql in a container
17+
18+
1. create a directory for our tutorial `mkdir getting-started-docker-mysql-nodejs`
19+
2. move to this directory `cd getting-started-docker-mysql-nodejs/`
20+
3. create a directory for our mysql microservice `mkdir mysql-microservice`
21+
4. move to this directory `cd mysql-microservice/`
22+
5. create a Dockerfile with following content (name of file will be `Dockerfile`)
23+
```
24+
## Pull the mysql:5.7 image
25+
FROM mysql:5.7
26+
27+
## The maintainer name and email
28+
MAINTAINER Your Name <name@email.com>
29+
30+
# database = test and password for root = password
31+
ENV MYSQL_DATABASE=test \
32+
MYSQL_ROOT_PASSWORD=password
33+
34+
# when container will be started, we'll have `test` database created with this schema
35+
COPY ./test-dump.sql /docker-entrypoint-initdb.d/
36+
37+
```
38+
6. we'll initialize our test database with a sample schema.
39+
Download [test-dump.sql](https://github.com/varunon9/getting-started-docker-mysql-nodejs/blob/master/mysql-microservice/test-dump.sql) and put it inside mysql-microservice folder along with Dockerfile
40+
41+
7. create a data directory where mysql will store its content `mkdir data`.
42+
We will specify this directory wile running our mysql container.
43+
On Linux default storage directory is `/var/lib/mysql` but in this tutorial we'll use a custom storage directory.
44+
45+
8. build the image with Dockerfile `docker build -t test-mysql .`
46+
Note that we are inside mysql-microservice directory. `test-mysql` would be name of our image
47+
48+
9. you can check your newly built image using `docker images`
49+
50+
10. run the newly created docker image as container
51+
```
52+
docker run -d \
53+
--publish 6603:3306 \
54+
--volume=/home/varunkumar/getting-started-docker-mysql-nodejs/mysql-microservice/data:/var/lib/mysql \
55+
--name=test-mysql-microservice test-mysql
56+
```
57+
58+
11. with above command we started our container in detach mode `-d` and mapped host(your machine) port 6603 with container port 3306 (mysql server) `--publish 6603:3306`.
59+
We are also using our custom data storage directory by specifying host path volume `--volume`.
60+
Replace `/home/varunkumar/getting-started-docker-mysql-nodejs/mysql-microservice/data` path to absolute path of data directory which you created on your system.
61+
We are also naming our container as test-mysql-microservice `--name`
62+
63+
12. check logs to see if everything went smooth `docker logs test-mysql-microservice`
64+
65+
13. check your container state `docker ps`
66+
67+
14. we have successfully launched a mysql container
68+
69+
70+
### connecting to newly launched mysql container from host (optional)
71+
72+
To verify that our test-mysql-microservice container is up and running, we'll connect to it.
73+
Follow below steps if you have mysql (mysql-client) installed on your system.
74+
75+
1. check the ip of your system. On Linux use `ifconfig`. Lets say that ip is 192.168.43.147
76+
2. connect to test-mysql-microservice container with following params-
77+
user-root, host=192.168.43.147, port=6603, database=test and password=password.
78+
Remember that we have specified root username and password in Dockerfile.
79+
Also our container is initialized with test-dump.sql (a schema with database name test)
80+
81+
3. `mysql -u root -p -h 192.168.43.147 -P 6603 -D test`
82+
use password=password when prompt and hit enter
83+
84+
4. if connected successfully you can see a sample table students `show tables`
85+
`exit` when done.
86+
87+
