From 194723f314f505de3d39afb7fd769bc02293fd88 Mon Sep 17 00:00:00 2001 From: 荒野無燈 Date: Tue, 10 Mar 2020 12:28:03 +0800 Subject: force run container detached if container CreateCommand missing the detach param MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit the podman generated systemd service file has `Type=forking` service, so the command after `ExecStart=` should not run in front. if someone created a container and has the detach(`-d`) param missing like this ``` podman create --name ngxdemo -P nginxdemos/hello ``` and generate the file with `--new` param: ``` podman generate systemd --name --new ngxdemo ``` because `podman run xxx` has no `-d` param, so the container is not run in background and nerver exit. and systemd will fail to start the service: ``` sudo systemctl start container-ngxdemo.service Job for container-ngxdemo.service failed because a timeout was exceeded. See "systemctl status container-ngxdemo.service" and "journalctl -xe" for details. ``` Signed-off-by: 荒野無燈 --- pkg/systemd/generate/systemdgen_test.go | 91 ++++++++++++++++++++++++++++++++- 1 file changed, 90 insertions(+), 1 deletion(-) (limited to 'pkg/systemd/generate/systemdgen_test.go') diff --git a/pkg/systemd/generate/systemdgen_test.go b/pkg/systemd/generate/systemdgen_test.go index 145296ea9..3c20dd8b9 100644 --- a/pkg/systemd/generate/systemdgen_test.go +++ b/pkg/systemd/generate/systemdgen_test.go @@ -132,13 +132,57 @@ After=network-online.target [Service] Restart=always ExecStartPre=/usr/bin/rm -f %t/%n-pid %t/%n-cid -ExecStart=/usr/bin/podman run --conmon-pidfile %t/%n-pid --cidfile %t/%n-cid --cgroups=no-conmon --name jadda-jadda --hostname hello-world awesome-image:latest command arg1 ... argN +ExecStart=/usr/bin/podman run --conmon-pidfile %t/%n-pid --cidfile %t/%n-cid --cgroups=no-conmon -d --name jadda-jadda --hostname hello-world awesome-image:latest command arg1 ... argN ExecStop=/usr/bin/podman stop --ignore --cidfile %t/%n-cid -t 42 ExecStopPost=/usr/bin/podman rm --ignore -f --cidfile %t/%n-cid PIDFile=%t/%n-pid KillMode=none Type=forking +[Install] +WantedBy=multi-user.target` + + goodNameNewDetach := `# jadda-jadda.service +# autogenerated by Podman CI + +[Unit] +Description=Podman jadda-jadda.service +Documentation=man:podman-generate-systemd(1) +Wants=network.target +After=network-online.target + +[Service] +Restart=always +ExecStartPre=/usr/bin/rm -f %t/%n-pid %t/%n-cid +ExecStart=/usr/bin/podman run --conmon-pidfile %t/%n-pid --cidfile %t/%n-cid --cgroups=no-conmon --detach --name jadda-jadda --hostname hello-world awesome-image:latest command arg1 ... argN +ExecStop=/usr/bin/podman stop --ignore --cidfile %t/%n-cid -t 42 +ExecStopPost=/usr/bin/podman rm --ignore -f --cidfile %t/%n-cid +PIDFile=%t/%n-pid +KillMode=none +Type=forking + +[Install] +WantedBy=multi-user.target` + + goodIdNew := `# container-639c53578af4d84b8800b4635fa4e680ee80fd67e0e6a2d4eea48d1e3230f401.service +# autogenerated by Podman CI + +[Unit] +Description=Podman container-639c53578af4d84b8800b4635fa4e680ee80fd67e0e6a2d4eea48d1e3230f401.service +Documentation=man:podman-generate-systemd(1) +Wants=network.target +After=network-online.target + +[Service] +Restart=always +ExecStartPre=/usr/bin/rm -f %t/%n-pid %t/%n-cid +ExecStart=/usr/bin/podman run --conmon-pidfile %t/%n-pid --cidfile %t/%n-cid --cgroups=no-conmon -d awesome-image:latest +ExecStop=/usr/bin/podman stop --ignore --cidfile %t/%n-cid -t 10 +ExecStopPost=/usr/bin/podman rm --ignore -f --cidfile %t/%n-cid +PIDFile=%t/%n-pid +KillMode=none +Type=forking + [Install] WantedBy=multi-user.target` @@ -230,6 +274,51 @@ WantedBy=multi-user.target` goodNameNew, false, }, + {"good with explicit short detach param", + ContainerInfo{ + Executable: "/usr/bin/podman", + ServiceName: "jadda-jadda", + ContainerName: "jadda-jadda", + RestartPolicy: "always", + PIDFile: "/var/run/containers/storage/overlay-containers/639c53578af4d84b8800b4635fa4e680ee80fd67e0e6a2d4eea48d1e3230f401/userdata/conmon.pid", + StopTimeout: 42, + PodmanVersion: "CI", + New: true, + CreateCommand: []string{"I'll get stripped", "container", "run", "-d", "--name", "jadda-jadda", "--hostname", "hello-world", "awesome-image:latest", "command", "arg1", "...", "argN"}, + }, + goodNameNew, + false, + }, + {"good with explicit full detach param", + ContainerInfo{ + Executable: "/usr/bin/podman", + ServiceName: "jadda-jadda", + ContainerName: "jadda-jadda", + RestartPolicy: "always", + PIDFile: "/var/run/containers/storage/overlay-containers/639c53578af4d84b8800b4635fa4e680ee80fd67e0e6a2d4eea48d1e3230f401/userdata/conmon.pid", + StopTimeout: 42, + PodmanVersion: "CI", + New: true, + CreateCommand: []string{"I'll get stripped", "container", "run", "--detach", "--name", "jadda-jadda", "--hostname", "hello-world", "awesome-image:latest", "command", "arg1", "...", "argN"}, + }, + goodNameNewDetach, + false, + }, + {"good with id and no param", + ContainerInfo{ + Executable: "/usr/bin/podman", + ServiceName: "container-639c53578af4d84b8800b4635fa4e680ee80fd67e0e6a2d4eea48d1e3230f401", + ContainerName: "639c53578af4d84b8800b4635fa4e680ee80fd67e0e6a2d4eea48d1e3230f401", + RestartPolicy: "always", + PIDFile: "/var/run/containers/storage/overlay-containers/639c53578af4d84b8800b4635fa4e680ee80fd67e0e6a2d4eea48d1e3230f401/userdata/conmon.pid", + StopTimeout: 10, + PodmanVersion: "CI", + New: true, + CreateCommand: []string{"I'll get stripped", "container", "run", "awesome-image:latest"}, + }, + goodIdNew, + false, + }, } for _, tt := range tests { test := tt -- cgit v1.2.3-54-g00ecf
