* Added optional container restore statisticsAdrian Reber2021-11-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the parameter '--print-stats' to 'podman container restore'. With '--print-stats' Podman will measure how long Podman itself, the OCI runtime and CRIU requires to restore a checkpoint and print out these information. CRIU already creates process restore statistics which are just read in addition to the added measurements. In contrast to just printing out the ID of the restored container, Podman will now print out JSON: # podman container restore --latest --print-stats { "podman_restore_duration": 305871, "container_statistics": [ { "Id": "47b02e1d474b5d5fe917825e91ac653efa757c91e5a81a368d771a78f6b5ed20", "runtime_restore_duration": 140614, "criu_statistics": { "forking_time": 5, "restore_time": 67672, "pages_restored": 14 } } ] } The output contains 'podman_restore_duration' which contains the number of microseconds Podman required to restore the checkpoint. The output also includes 'runtime_restore_duration' which is the time the runtime needed to restore that specific container. Each container also includes 'criu_statistics' which displays the timing information collected by CRIU. Signed-off-by: Adrian Reber <areber@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new boltdb to handle IPAM assignment. The db structure is the following: Each network has their own bucket with the network name as bucket key. Inside the network bucket there is an ID bucket which maps the container ID (key) to a json array of ip addresses (value). The network bucket also has a bucket for each subnet, the subnet is used as key. Inside the subnet bucket an ip is used as key and the container ID as value. The db should be stored on a tmpfs to ensure we always have a clean state after a reboot. Signed-off-by: Paul Holzinger <pholzing@redhat.com>

I spent quite a bit of time trying to diagnose what disk, partition, overlay, etc. was filling up before I realised this was actually due to leaking from failing containers.

So if a users forwards a range of 1k ports with podman run -p 1001-2000 we have to store each of the thousand ports individually as array element. This bloats the db and makes the JSON encoding and decoding much slower. In many places we already use a better port struct type which supports ranges, e.g. `pkg/specgen` or the new network interface. Because of this we have to do many runtime conversions between the two port formats. If everything uses the new format we can skip the runtime conversions. This commit adds logic to replace all occurrences of the old format with the new one. The database will automatically migrate the ports to new format when the container config is read for the first time after the update. The `ParsePortMapping` function is `pkg/specgen/generate` has been reworked to better work with the new format. The new logic is able to deduplicate the given ports. This is necessary the ensure we store them efficiently in the DB. The new code should also be more performant than the old one. To prove that the code is fast enough I added go benchmarks. Parsing 1 million ports took less than 0.5 seconds on my laptop. Benchmark normalize PortMappings in specgen: Please note that the 1 million ports are actually 20x 50k ranges because we cannot have bigger ranges than 65535 ports. ``` $ go test -bench=. -benchmem ./pkg/specgen/generate/ goos: linux goarch: amd64 pkg: github.com/containers/podman/v3/pkg/specgen/generate cpu: Intel(R) Core(TM) i7-10850H CPU @ 2.70GHz BenchmarkParsePortMappingNoPorts-12 480821532 2.230 ns/op 0 B/op 0 allocs/op BenchmarkParsePortMapping1-12 38972 30183 ns/op 131584 B/op 9 allocs/op BenchmarkParsePortMapping100-12 18752 60688 ns/op 141088 B/op 315 allocs/op BenchmarkParsePortMapping1k-12 3104 331719 ns/op 223840 B/op 3018 allocs/op BenchmarkParsePortMapping10k-12 376 3122930 ns/op 1223650 B/op 30027 allocs/op BenchmarkParsePortMapping1m-12 3 390869926 ns/op 124593840 B/op 4000624 allocs/op BenchmarkParsePortMappingReverse100-12 18940 63414 ns/op 141088 B/op 315 allocs/op BenchmarkParsePortMappingReverse1k-12 3015 362500 ns/op 223841 B/op 3018 allocs/op BenchmarkParsePortMappingReverse10k-12 343 3318135 ns/op 1223650 B/op 30027 allocs/op BenchmarkParsePortMappingReverse1m-12 3 403392469 ns/op 124593840 B/op 4000624 allocs/op BenchmarkParsePortMappingRange1-12 37635 28756 ns/op 131584 B/op 9 allocs/op BenchmarkParsePortMappingRange100-12 39604 28935 ns/op 131584 B/op 9 allocs/op BenchmarkParsePortMappingRange1k-12 38384 29921 ns/op 131584 B/op 9 allocs/op BenchmarkParsePortMappingRange10k-12 29479 40381 ns/op 131584 B/op 9 allocs/op BenchmarkParsePortMappingRange1m-12 927 1279369 ns/op 143022 B/op 164 allocs/op PASS ok github.com/containers/podman/v3/pkg/specgen/generate 25.492s ``` Benchmark convert old port format to new one: ``` go test -bench=. -benchmem ./libpod/ goos: linux goarch: amd64 pkg: github.com/containers/podman/v3/libpod cpu: Intel(R) Core(TM) i7-10850H CPU @ 2.70GHz Benchmark_ocicniPortsToNetTypesPortsNoPorts-12 663526126 1.663 ns/op 0 B/op 0 allocs/op Benchmark_ocicniPortsToNetTypesPorts1-12 7858082 141.9 ns/op 72 B/op 2 allocs/op Benchmark_ocicniPortsToNetTypesPorts10-12 2065347 571.0 ns/op 536 B/op 4 allocs/op Benchmark_ocicniPortsToNetTypesPorts100-12 138478 8641 ns/op 4216 B/op 4 allocs/op Benchmark_ocicniPortsToNetTypesPorts1k-12 9414 120964 ns/op 41080 B/op 4 allocs/op Benchmark_ocicniPortsToNetTypesPorts10k-12 781 1490526 ns/op 401528 B/op 4 allocs/op Benchmark_ocicniPortsToNetTypesPorts1m-12 4 250579010 ns/op 40001656 B/op 4 allocs/op PASS ok github.com/containers/podman/v3/libpod 11.727s ``` Signed-off-by: Paul Holzinger <pholzing@redhat.com>
* | | Fix swagger definition for the new mac address typePaul Holzinger2021-11-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new mac address type broke the api docs. While we could successfully generate the swagger file it could not be viewed in a browser. The problem is that the swagger generation create two type definitions with the name `HardwareAddr` and this pointed back to itself. Thus the render process was stucked in an endless loop. To fix this manually rename the new type to MacAddress and overwrite the types to string because the json unmarshaller accepts the mac as string. Signed-off-by: Paul Holzinger <pholzing@redhat.com>

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | The check if cleanup is needed reads all container and checks if there are running containers with bridge networking. If we do not find any we have to cleanup the ns. However there was a problem with this because the state is empty by default so the running check never worked. Fortunately the was a second check which relies on the CNI files so we still did cleanup anyway. With netavark I noticed that this check is broken because the CNI files were not present.

Consider `VOLUME ['/etc/foo', '/etc/bar']` in a Containerfile. While it looks correct to the human eye, the single quotes are wrong and yield the two volumes to be `[/etc/foo,` and `/etc/bar]` in Podman and Docker. When running the container, it'll create a directory `bar]` in `/etc` and a directory `[` in `/` with two subdirectories `etc/foo,`. This behavior is surprising to me but how Docker behaves. We may improve on that in the future. Note that the correct way to syntax for volumes in a Containerfile is `VOLUME /A /B /C` or `VOLUME ["/A", "/B", "/C"]`; single quotes are not supported. This change restores this behavior without breaking container creation or ending up in an infinite loop.
