I have two python files, testing_1.py and testing_2.py. Then, I have created the configmap with testing-config1 to store testing_1.py and testing-config2 to store testing_2.py respectively.
In Kubernetes yaml,
...
containers:
- name: spark-master
image: bde2020/spark-master:2.4.4-hadoop2.7
volumeMounts:
- name: testing
mountPath: /jobs
- name: testing2
mountPath: /jobs
volumes:
- name: testing
configMap:
name: testing-config1
- name: testing2
configMap:
name: testing-config2
...In the final result, the path only contains testing_1.py.
You can do it by providing subPath while specifying path. Change it as below:
containers:
- name: spark-master
image: bde2020/spark-master:2.4.4-hadoop2.7
volumeMounts:
- name: testing
mountPath: /jobs/testing_1.py
subPath: testing_1.py
- name: testing2
mountPath: /jobs/testing_2.py
subPath: testing_2.py
volumes:
- name: testing
configMap:
name: testing-config1
- name: testing2
configMap:
name: testing-config2You can put both files in the same ConfigMap.
Or, use a projected volume:
A projected volume maps several existing volume sources into the same directory.
Currently, the following types of volume sources can be projected:
- secret
- downwardAPI
- configMap
- serviceAccountToken
