如何在OpenShift中使用“oc new-app”为docker run提供参数？

Question

When I run some docker containers, I need to provide parameters on the command line ( docker run image some-parameters ). How can I provide the same parameters when using oc new-app in OpenShift Origin?

Answer 1

The oc new-app example includes:

# Create an application based on a template file, explicitly setting a parameter value
$ oc new-app --file=./example/myapp/template.json --param=MYSQL_USER=admin

The --param option can be useful here.

Note: The oc run example include:

# Start a single instance of nginx, but overload the spec of the replication
# controller with a partial set of values parsed from JSON.
$ oc run nginx --image=nginx --overrides='{ "apiVersion": "v1", "spec": { ... } }'

That json can include a parameter section, as does this one used by sti_incremental.go#L39 .

Answer 2

Based on Openshift Client help

oc run -h

oc run NAME --image=image [--env="key=value"] [--port=port] [--replicas=replicas] [--dry-run=bool] [--overrides=inline-json] [--command] -- [COMMAND] [args...] [options]

For me worked this:

oc run my_command --image='alpine' --command -- telnet some_server 22
