Was following along with Spring + Kotlin = Modern + Reactive + Productive presentation on YouTube! by creating a Kotlin-based Spring Web Flux Reactive app using https://start.spring.io/...
Generated the project using these dependencies (please note the Spring Boot and Java versions, as well):
This generated the build.gradle.kts
file:
plugins {
java
id("org.springframework.boot") version "3.0.6"
id("io.spring.dependency-management") version "1.1.0"
id("org.graalvm.buildtools.native") version "0.9.20"
}
group = "bootiful"
version = "0.0.1-SNAPSHOT"
java.sourceCompatibility = JavaVersion.VERSION_17
repositories {
mavenCentral()
}
extra["testcontainersVersion"] = "1.18.1"
dependencies {
implementation("org.springframework.boot:spring-boot-starter-data-r2dbc")
implementation("org.springframework.boot:spring-boot-starter-webflux")
runtimeOnly("org.postgresql:postgresql")
runtimeOnly("org.postgresql:r2dbc-postgresql")
testImplementation("org.springframework.boot:spring-boot-starter-test")
testImplementation("io.projectreactor:reactor-test")
testImplementation("org.testcontainers:junit-jupiter")
testImplementation("org.testcontainers:postgresql")
testImplementation("org.testcontainers:r2dbc")
}
dependencyManagement {
imports {
mavenBom("org.testcontainers:testcontainers-bom:${property("testcontainersVersion")}")
}
}
tasks.withType<Test> {
useJUnitPlatform()
}
Was getting an error when I tried to build it initially (after downloading & extracting the zip file) using gradle build
& ./gradlew build
on macOS (both using IntelliJ & command line).
When I cloned the GitHub project that this presentation was based on, I got the same exact error:
Using gradle build
(also fails when using the wrapper e.g. ./gradlew build
):

Why can’t I build this when I do a fresh git clone
from the repository?
This is the project I am trying to build:
https://github.com/jamesward/nks/tree/main/bootiful
docker daemon was running, I ran the following command (before I tried building with gradle build
and/or ./gradlew build
)
docker ps
:
output:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
Like, I said this also happened when I created a new project from within http://start.spring.io. Is this due to TestContainers? Is there any steps/prerequisites required for TestContainers or any other config to be set?
After running the Unix shell script located here:
https://github.com/jamesward/nks/blob/main/postgres.sh
And then checking the docker daemon:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

The Unix shell script’s tail end:

When I look inside: ../build/reports/tests/test/index.html
:

Would appreciate it if someone else could try to replicate this issue…
Remember, this doesn’t work when I created a project via http://start.spring.io using the same dependencies (see screenshot above) that the presenters in the YouTube presentation video used nor did the author’s code work when I did a fresh git clone
…

After running
./gradlew build --info
, the output was something similar to:Fixed this by running this from the command line:
sudo ln -s $HOME/.docker/run/docker.sock /var/run/docker.sock
Courtesy of a comment someone answered to this SO post:
Test Container test cases are failing due to "Could not find a valid Docker environment"
Now, when I run
./gradlew build
:According to your stacktrace, the issue you are experiencing is related to Docker:
The line 256 in
DockerClientProviderStrategy
has the following code:Did you have the opportunity to try the instructions provided here? https://www.testcontainers.org/on_failure.html
https://www.testcontainers.org/supported_docker_environment/
My suggestion would be to try updating or reinstalling Docker. This could potentially solve the issue.
