From d28e85741fedb89be48a03d4f05687e970eb71b9 Mon Sep 17 00:00:00 2001 From: cdoern Date: Wed, 14 Jul 2021 16:30:28 -0400 Subject: InfraContainer Rework InfraContainer should go through the same creation process as regular containers. This change was from the cmd level down, involving new container CLI opts and specgen creating functions. What now happens is that both container and pod cli options are populated in cmd and used to create a podSpecgen and a containerSpecgen. The process then goes as follows FillOutSpecGen (infra) -> MapSpec (podOpts -> infraOpts) -> PodCreate -> MakePod -> createPodOptions -> NewPod -> CompleteSpec (infra) -> MakeContainer -> NewContainer -> newContainer -> AddInfra (to pod state) Signed-off-by: cdoern --- cmd/podman/common/specgen.go | 972 ------------------------------------------- 1 file changed, 972 deletions(-) delete mode 100644 cmd/podman/common/specgen.go (limited to 'cmd/podman/common/specgen.go') diff --git a/cmd/podman/common/specgen.go b/cmd/podman/common/specgen.go deleted file mode 100644 index 59d32f568..000000000 --- a/cmd/podman/common/specgen.go +++ /dev/null @@ -1,972 +0,0 @@ -package common - -import ( - "fmt" - "os" - "strconv" - "strings" - "time" - - "github.com/containers/image/v5/manifest" - "github.com/containers/podman/v3/cmd/podman/parse" - "github.com/containers/podman/v3/libpod/define" - ann "github.com/containers/podman/v3/pkg/annotations" - envLib "github.com/containers/podman/v3/pkg/env" - ns "github.com/containers/podman/v3/pkg/namespaces" - "github.com/containers/podman/v3/pkg/specgen" - systemdDefine "github.com/containers/podman/v3/pkg/systemd/define" - "github.com/containers/podman/v3/pkg/util" - "github.com/docker/go-units" - "github.com/opencontainers/runtime-spec/specs-go" - "github.com/pkg/errors" -) - -func getCPULimits(c *ContainerCLIOpts) *specs.LinuxCPU { - cpu := &specs.LinuxCPU{} - hasLimits := false - - if c.CPUS > 0 { - period, quota := util.CoresToPeriodAndQuota(c.CPUS) - - cpu.Period = &period - cpu.Quota = "a - hasLimits = true - } - if c.CPUShares > 0 { - cpu.Shares = &c.CPUShares - hasLimits = true - } - if c.CPUPeriod > 0 { - cpu.Period = &c.CPUPeriod - hasLimits = true - } - if c.CPUSetCPUs != "" { - cpu.Cpus = c.CPUSetCPUs - hasLimits = true - } - if c.CPUSetMems != "" { - cpu.Mems = c.CPUSetMems - hasLimits = true - } - if c.CPUQuota > 0 { - cpu.Quota = &c.CPUQuota - hasLimits = true - } - if c.CPURTPeriod > 0 { - cpu.RealtimePeriod = &c.CPURTPeriod - hasLimits = true - } - if c.CPURTRuntime > 0 { - cpu.RealtimeRuntime = &c.CPURTRuntime - hasLimits = true - } - - if !hasLimits { - return nil - } - return cpu -} - -func getIOLimits(s *specgen.SpecGenerator, c *ContainerCLIOpts) (*specs.LinuxBlockIO, error) { - var err error - io := &specs.LinuxBlockIO{} - hasLimits := false - if b := c.BlkIOWeight;
