From 2aa3261744b4247996abf3ef552e03a89f77cfb8 Mon Sep 17 00:00:00 2001 From: Adrian Reber Date: Tue, 5 Feb 2019 16:26:30 +0000 Subject: Add test case for container migration The difference between container checkpoint/restore and container migration is that for migration the container which was checkpointed must not exist during restore. To simulate migration the container is remove ('podman rm -fa') before being restored. The migration test does following steps: * podman run * podman container checkpoint -l -e /tmp/checkpoint.tar.gz * podman rm -fa * podman container restore -i /tmp/checkpoint.tar.gz Signed-off-by: Adrian Reber --- test/e2e/checkpoint_test.go | 34 ++++++++++++++++++++++++++++++++++ 1 file changed, 34 insertions(+) diff --git a/test/e2e/checkpoint_test.go b/test/e2e/checkpoint_test.go index 95ec21433..bd9cdcb8d 100644 --- a/test/e2e/checkpoint_test.go +++ b/test/e2e/checkpoint_test.go @@ -347,4 +347,38 @@ var _ = Describe("Podman checkpoint", func() { Expect(podmanTest.NumberOfContainersRunning()).To(Equal(0)) }) + // This test does the same steps which are necessary for migrating + // a container from one host to another + It("podman checkpoint container with export (migration)", func() { + // CRIU does not work with seccomp correctly on RHEL7 + session := podmanTest.Podman([]string{"run", "-it", "--security-opt", "seccomp=unconfined", "-d", ALPINE, "top"}) + session.WaitWithDefaultTimeout() + Expect(session.ExitCode()).To(Equal(0)) + Expect(podmanTest.NumberOfContainersRunning()).To(Equal(1)) + + result := podmanTest.Podman([]string{"container", "checkpoint", "-l", "-e", "/tmp/checkpoint.tar.gz"}) + result.WaitWithDefaultTimeout() + + Expect(result.ExitCode()).To(Equal(0)) + Expect(podmanTest.NumberOfContainersRunning()).To(Equal(0)) + Expect(podmanTest.GetContainerStatus()).To(ContainSubstring("Exited")) + + // Remove all containers to simulate migration + result = podmanTest.Podman([]string{"rm", "-fa"}) + result.WaitWithDefaultTimeout() + Expect(result.ExitCode()).To(Equal(0)) + Expect(podmanTest.NumberOfContainersRunning()).To(Equal(0)) + + result = podmanTest.Podman([]string{"container", "restore", "-i", "/tmp/checkpoint.tar.gz"}) + result.WaitWithDefaultTimeout() + + Expect(result.ExitCode()).To(Equal(0)) + Expect(podmanTest.NumberOfContainersRunning()).To(Equal(1)) + Expect(podmanTest.GetContainerStatus()).To(ContainSubstring("Up")) + + result = podmanTest.Podman([]string{"rm", "-fa"}) + result.WaitWithDefaultTimeout() + Expect(result.ExitCode()).To(Equal(0)) + Expect(podmanTest.NumberOfContainersRunning()).To(Equal(0)) + }) }) -- cgit v1.2.3-54-g00ecf
