This repository offers utility functions for easy integrating go applications in kubernetes
Works for both client side and in-cluster testing.
Lets say you'd like to spin up your test environment, run integration tests and cleanup everything, this is all you have to do:
func TestMinioTemplate(t *testing.T) {
g := Goblin(t)
RegisterFailHandler(func(m string, _ ...int) { g.Fail(m) })
podName := "minio-simple-test"
endpoint := "localhost:9000"
accessKey := "AKIAIOSFODNN7EXAMPLE"
secretKey := "wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY"
l := New()
g.Describe("minio", func() {
g.After(func() {
// tear down
l.Cleanup()
})
g.It("should be ready to connect", func() {
// request whatever we need
l.CreateAndForwardMinio(config.NAMESPACE, podName, accessKey, secretKey)
minioClient, err := minio.New(endpoint, accessKey, secretKey, false)
if err != nil {
t.Fatal(err)
}
_, err = minioClient.ListBuckets()
if err != nil {
t.Fatal(err)
}
})
})
}Your environment might be a bit more complex. Working with multiple pods is as easy as:
func TestCreateAndForwardPods(t *testing.T) {
g := Goblin(t)
RegisterFailHandler(func(m string, _ ...int) { g.Fail(m) })
g.Describe("CreateAndForwardPods", func() {
l := New()
g.After(func() {
l.Cleanup()
})
minioPodName := "minio-multitest"
endpoint := "localhost:9000"
accessKey := "AKIAIOSFODNN7EXAMPLE"
secretKey := "wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY"
postgresPodName := "postgres-multitest"
dsn := "postgresql://postgres@localhost:15432/postgres?sslmode=disable"
g.It("should provide minio + postgres", func() {
l.CreateAndForwardPods(config.NAMESPACE,
podtemplates.Minio(minioPodName, accessKey, secretKey),
podtemplates.Postgresql(postgresPodName),
)
minioClient, err := minio.New(endpoint, accessKey, secretKey, false)
if err != nil {
t.Fatal(err)
}
_, err = minioClient.ListBuckets()
if err != nil {
t.Fatal(err)
}
db, err := sql.Open("postgres", dsn)
if err != nil {
t.Fatal(err)
}
defer db.Close()
Expect(db.Ping()).To(BeNil())
})
})
}go test ./pkg/... -namespace=defaultFeel free to submit additions (e.g. more pod templates) via pull requests. Don't forget to add tests.
