HTTP(S) Wait strategy

The HTTP wait strategy will check the result of an HTTP(S) request against the container and allows to set the following conditions:

• the port to be used.
• the path to be used.
• the HTTP method to be used.
• the HTTP request body to be sent.
• the HTTP status code matcher as a function.
• the HTTP response matcher as a function.
• the TLS config to be used for HTTPS.
• the startup timeout to be used in seconds, default is 60 seconds.
• the poll interval to be used in milliseconds, default is 100 milliseconds.

Variations on the HTTP wait strategy are supported, including:

Match an HTTP method

req := ContainerRequest{
        Image:        "docker.io/nginx:alpine",
        ExposedPorts: []string{"8086/tcp"},
        WaitingFor: wait.ForHTTP("/ping").WithMethod(http.MethodPost).WithBody(bytes.NewReader([]byte("ping"))),
    }

Match an HTTP status code

req := ContainerRequest{
        Image:        "docker.io/nginx:alpine",
        ExposedPorts: []string{"8086/tcp"},
        WaitingFor: wait.ForHTTP("/ping").WithPort("8086/tcp").WithStatusCodeMatcher(
            func(status int) bool {
                return status == http.StatusNoContent
            },
        ),
    }

Match an HTTPS status code and a response matcher

req := testcontainers.ContainerRequest{
    FromDockerfile: testcontainers.FromDockerfile{
        Context: workdir + "/testdata",
    },
    ExposedPorts: []string{"80/tcp"},
    WaitingFor: wait.NewHTTPStrategy("/ping").
        WithStartupTimeout(time.Second * 10).WithPort("80/tcp").
        WithResponseMatcher(func(body io.Reader) bool {
            data, _ := ioutil.ReadAll(body)
            return bytes.Equal(data, []byte("pong"))
        }).
        WithStatusCodeMatcher(func(status int) bool {
            i++ // always fail the first try in order to force the polling loop to be re-run
            return i > 1 && status == 200
        }).
        WithMethod(http.MethodPost).WithBody(bytes.NewReader([]byte("ping"))),
}
