In our ci builds we see random failures every other build saying a container can't be started. Our scenario is the following:

  • We have a container running our application
  • We have another container (BrowserWebDriverContainer) to run chrome
  • We have specified a network for both
  • The chrome container depends on the application container.

The code looks like this:

private void createContainers() {
	Network network = Network.newNetwork();
	GenericContainer<?> applicationContainer = new ApplicationContainer();
	applicationContainer.withNetwork(network).withNetworkAliases("app").withExposedPorts(8080, 8443);

	BrowserWebDriverContainer<?> chrome = new BrowserWebDriverContainer<>(
			DockerImageName.parse("selenium/standalone-chrome-debug:3.141.59-20210713")
					.asCompatibleSubstituteFor("selenium/standalone-chrome-debug"));
	chrome.withNetwork(network).withRecordingMode(VncRecordingMode.SKIP, null).dependsOn(applicationContainer);
	
	chrome.start();
}

In this scenario, ApplicationContainer extends GenericContainer<ApplicationContainer>. The code works most of the time. As said, every now and then we see the following error which makes the test run fail.

We are using testcontainers 1.15.3 right now.
