How can I store a binary file in a Kubernetes ConfigMap?
<p>Can one store a binary file in a <a href="http://kubernetes.io/" rel="noreferrer">Kubernetes</a> <a href="http://kubernetes.io/docs/user-guide/configmap/" rel="noreferrer">ConfigMap</a> and then later read the same content from a volume that mounts this ConfigMap?  For example, if directory <code>/etc/mycompany/myapp/config</code> contains binary file <code>keystore.jks</code>, will</p>

<pre><code>kubectl create configmap myapp-config --from-file=/etc/mycompany/myapp/config
</code></pre>

<p>include file <code>keystore.jks</code> in ConfigMap <code>myapp-config</code> that can later be mapped to a volume, mounted into a container, and read as a binary file?</p>

<p>For example, given the following pod spec, should <code>keystore.jks</code> be available to <code>myapp</code> at <code>/etc/mycompany/myapp/config/keystore.jks</code>?</p>

<pre><code>apiVersion: v1
kind: Pod
metadata:
  name: myapp
spec:
  containers:
  - name: myapp
    image: mycompany/myapp
    volumeMounts:
    - name: myapp-config
      mountPath: /etc/mycompany/myapp/config

  volumes:
  - name: myapp-config
    configMap:
      name: myapp-config
</code></pre>
