how to create container with memory limit in docker go client - docker

Question

I am trying to create a container with memory limit using the docker go client - https://godoc.org/github.com/docker/docker/client#Client.ContainerCreate
However I cannot figure out where to add these parameters in the function.
docker run -m 250m --name test repo/tag
In the docker api, it comes under Host Config structure but in go doc I saw the option under resources which is used in HostConfig - https://godoc.org/github.com/docker/docker/api/types/container#HostConfig
Calling like this
import(
....
"github.com/docker/docker/api/types"
"github.com/docker/docker/api/types/container"
"github.com/docker/docker/api/types/events"
"github.com/docker/docker/api/types/filters"
"github.com/docker/docker/client"
"github.com/docker/go-connections/nat"
)
...
resp, err1 := cli.ContainerCreate(ctx,
&container.Config{
User: strconv.Itoa(os.Getuid()), // avoid permission issues
Image: cfg.ImageName,
AttachStdin: false,
AttachStdout: true,
AttachStderr: true,
Tty: true,
ExposedPorts: exposedPorts,
Labels: labels,
Env: envVars,
},
&container.HostConfig{
Binds: binds,
NetworkMode: container.NetworkMode(cfg.Network),
PortBindings: nat.PortMap{
"1880": []nat.PortBinding{
nat.PortBinding{
HostIP: "",
HostPort: "1880",
},
}},
AutoRemove: true,
Memory : 262144000, //this does not work
},
nil, // &network.NetworkingConfig{},
name,
)
unknown field 'Memory' in struct literal of type container.HostConfig. Since it does not have a field name and only type I have no idea how to add resources to Hostconfig. Any help is appreciated - I am a newbie at go and am trying to tweak an opensource project I was using - redzilla - due to my system's resource constraints

You can define memory limit using Resources field of HostConfig struct.
Resources: container.Resources{ Memory:3e+7 }
