With podman play kube, podman would always attempt to pull if the image has the :latest tag. But this would fail if the image was built locally and given latest as the tag. Images build with podman and buildah have localhost as the domain, so check if the domain is localhost. If that is the case, then don't attempt a pull.

## NAME
|
|
podman-play-kube - Create pods and containers based on Kubernetes YAML
|
|
|
|
## SYNOPSIS
|
|
**podman play kube** [*options*] *file*__.yml__
|
|
|
|
## DESCRIPTION
|
|
**podman play kube** will read in a structured file of Kubernetes YAML. It will then recreate
|
|
the pod and containers described in the YAML. The containers within the pod are then started and
|
|
the ID of the new Pod is output.
|
|
|
|
Ideally the input file would be one created by Podman (see podman-generate-kube(1)). This would guarantee a smooth import and expected results.
|
|
|
|
Note: HostPath volume types created by play kube will be given an SELinux private label (Z)
|
|
|
|
Note: If the `:latest` tag is used, Podman will attempt to pull the image from a registry. If the image was built locally with Podman or Buildah, it will have `localhost` as the domain, in that case, Podman will use the image from the local store even if it has the `:latest` tag.
|
|
|
|
## OPTIONS
|
|
|
|
#### **--authfile**=*path*
|
|
|
|
Path of the authentication file. Default is ${XDG\_RUNTIME\_DIR}/containers/auth.json, which is set using `podman login`.
|
|
If the authorization state is not found there, $HOME/.docker/config.json is checked, which is set using `docker login`.
|
|
|
|
Note: You can also override the default path of the authentication file by setting the REGISTRY\_AUTH\_FILE
|
|
environment variable. `export REGISTRY_AUTH_FILE=path`
|
|
|
|
#### **--cert-dir**=*path*
|
|
|
|
Use certificates at *path* (\*.crt, \*.cert, \*.key) to connect to the registry.
|
|
Default certificates directory is _/etc/containers/certs.d_. (Not available for remote commands)
|
|
|
|
#### **--configmap**=*path*
|
|
|
|
Use Kubernetes configmap YAML at path to provide a source for environment variable values within the containers of the pod.
|
|
|
|
Note: The *--configmap* option can be used multiple times or a comma-separated list of paths can be used to pass multiple Kubernetes configmap YAMLs.
|
|
|
|
#### **--creds**
|
|
|
|
The [username[:password]] to use to authenticate with the registry if required.
|
|
If one or both values are not supplied, a command line prompt will appear and the
|
|
value can be entered. The password is entered without echo.
|
|
|
|
#### **--log-driver**=driver
|
|
|
|
Set logging driver for all created containers.
|
|
|
|
#### **--network**=*networks*, **--net**
|
|
|
|
A comma-separated list of the names of CNI networks the pod should join.
|
|
|
|
#### **--quiet**, **-q**
|
|
|
|
Suppress output information when pulling images
|
|
|
|
#### **--seccomp-profile-root**=*path*
|
|
|
|
Directory path for seccomp profiles (default: "/var/lib/kubelet/seccomp"). (Not available for remote commands)
|
|
|
|
#### **--start**=*true|false*
|
|
|
|
Start the pod after creating it, set to false to only create it.
|
|
|
|
#### **--tls-verify**=*true|false*
|
|
|
|
Require HTTPS and verify certificates when contacting registries (default: true). If explicitly set to true,
|
|
then TLS verification will be used. If set to false, then TLS verification will not be used. If not specified,
|
|
TLS verification will be used unless the target registry is listed as an insecure registry in registries.conf.
|
|
|
|
#### **--help**, **-h**
|
|
|
|
Print usage statement
|
|
|
|
## EXAMPLES
|
|
|
|
Recreate the pod and containers as described in a file called `demo.yml`
|
|
```
|
|
$ podman play kube demo.yml
|
|
52182811df2b1e73f36476003a66ec872101ea59034ac0d4d3a7b40903b955a6
|
|
```
|
|
|
|
Provide `configmap-foo.yml` and `configmap-bar.yml` as sources for environment variables within the containers.
|
|
```
|
|
$ podman play kube demo.yml --configmap configmap-foo.yml,configmap-bar.yml
|
|
52182811df2b1e73f36476003a66ec872101ea59034ac0d4d3a7b40903b955a6
|
|
|
|
$ podman play kube demo.yml --configmap configmap-foo.yml --configmap configmap-bar.yml
|
|
52182811df2b1e73f36476003a66ec872101ea59034ac0d4d3a7b40903b955a6
|
|
```
|
|
|
|
CNI network(s) can be specified as comma-separated list using ``--network``
|
|
```
|
|
$ podman play kube demo.yml --network cni1,cni2
|
|
52182811df2b1e73f36476003a66ec872101ea59034ac0d4d3a7b40903b955a6
|
|
```
|
|
|
|
Please take into account that CNI networks must be created first using podman-network-create(1).
