1 | # Spring Boot Application Helm Chart Example
2 |
3 | ## Build docker image (JVM)
4 |
5 | Rename ```image``` in [demoweb/docker-compose.yml](demoweb/docker-compose.yml).
6 |
7 | ```yaml
8 | build:
9 | context: .
10 | image: binblee/springboot-helm-chart:jre-17
11 | ```
12 |
13 | Build docker image use docker-compose command.
14 |
15 | ```
16 | ➜ cd demoweb
17 | ➜ docker compose build
18 | ➜ docker push xxxx
19 | ```
20 |
21 | Unit test:
22 | ```
23 | ➜ cd demoweb
24 | ➜ docker compose up -d web
25 | ```
26 |
27 | Visit http://localhost:8080/ you should get 'Hello World.'
28 |
29 | Shut it down:
30 | ```
31 | ➜ docker compose down
32 | ```
33 |
34 |
35 | If you prefer to use docker to build image:
36 |
37 | ```
38 | ➜ cd demoweb
39 | ➜ docker build -t xxxx .
40 | ➜ docker push xxxx
41 | ```
42 |
43 | ## Build docker image (GraalVM)
44 |
45 | Springboot 3.0 supports build native exectuable using GraalVM, we can leverage this feature to build a native executable docker image.
46 |
47 | ```
48 | ➜ cd demoweb
49 | ➜ docker compose build web-graalvm
50 | ```
51 |
52 | [demoweb/docker-compose.yml](demoweb/docker-compose.yml) will tell you that native docker image is built with another Dockerfile: [demoweb/Dockerfile.graalvm](demoweb/Dockerfile.graalvm).
53 |
54 | Also to be noted that a native plugin is added to [demoweb/pom.xml](demoweb/pom.xml)
55 | ```
56 |
57 | org.graalvm.buildtools
58 | native-maven-plugin
59 |
60 | ```
61 |
62 | You can up and run two images with one command:
63 | ```
64 | ➜ cd demoweb
65 | ➜ docker compose up -d
66 | ```
67 |
68 | You should get two healthy containers:
69 | ```
70 | NAME COMMAND SERVICE STATUS PORTS
71 | demoweb-web-1 "sh -c 'java $JAVA_O…" web running (healthy) 0.0.0.0:8080->8080/tcp
72 | demoweb-web-graalvm-1 "/demoweb" web-graalvm running (healthy) 0.0.0.0:8888->8888/tcp
73 | ```
74 |
75 | Test JVM version with [http://localhost:8080](http://localhost:8080), while GraalVM version with [http://localhost:8888](http://localhost:8888)
76 |
77 |
78 | ## Deploy using helm
79 |
80 | Rename image ```image.repository``` and ```tag``` in [demoweb/charts/springboot-demoweb/values.yaml](demoweb/charts/springboot-demoweb/values.yaml) with your image name and tag.
81 |
82 | ```yaml
83 | image:
84 | repository: binblee/springboot-helm-chart
85 | tag: graalvm-22.3-java17
86 | ```
87 |
88 |
89 |
90 |
91 | You should have a running Kubernetes cluster and [helm installed](https://docs.helm.sh/using_helm/#installing-helm) before proceed.
92 |
93 |
94 |
95 | Deploy application using helm.
96 |
97 | ```
98 | ➜ cd demoweb/charts
99 | ➜ helm install demo ./springboot-demoweb/
100 | ```
101 |
102 | Run port-forward and test it:
103 | ```
104 | ➜ kubectl port-forward service/demo-springboot-demoweb 8080:80
105 | ➜ curl http://localhost:8080
106 | ```
107 | You should see "Hello World."
108 |
109 | Uninstall demo application in cluster:
110 | ```
111 | ➜ helm uninstall demo
112 | ```
113 |
114 | ## JVM image vs GraalVM image
115 |
116 | We have two docker images now, one is build with JVM, the other one is build with graalvm native-image. Size of native exectuable image is about 1/3 of the classic JVM one. Quite impressive.
117 |
118 | ```
119 | springboot-helm-chart:jre-17 294MB
120 | springboot-helm-chart:graalvm-22.3 78.9MB
121 | ```
122 |
123 | For more details, please refer to [https://docs.spring.io/spring-boot/docs/current/reference/html/native-image.html#native-image](https://docs.spring.io/spring-boot/docs/current/reference/html/native-image.html#native-image)
