Phpldapadmin pod fails with "No such file or directory" error

[eromanova]

Description I'm using kubernetes to deploy phpLDAPadmin. If I set --copy-service argument in phpLDAPadmin deployment, pod fails with No such file or directory: '/container/service/:runit/download.sh'")] error. Steps to reproduce Create deployment.yaml file with configuration below and run kubectl create -f deployment.yaml

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: phpldapadmin
  labels:
    app: phpldapadmin
spec:
  replicas: 1
  selector:
    matchLabels:
      app: phpldapadmin
  template:
    metadata:
      name: phpldapadmin
      labels:
        app: phpldapadmin
    spec:
      initContainers:
      containers:
      - name: ldap
        image: docker.io/osixia/phpldapadmin:0.7.1
        imagePullPolicy: Always
        args: ["--copy-service"]
        env:
        - name: PHPLDAPADMIN_HTTPS
          value: "false"
        - name: PHPLDAPADMIN_LDAP_HOSTS
          value: ldap

Expected result PhpLDAPadmin pod status is RUNNING.

Actual result Pod fails with CrashLoopBackOff status.

shutil.Error: [('/container/service/:runit/download.sh', '/container/run/service/:runit/download.sh', "[Errno 2] No such file or directory: '/container/service/:runit/download.sh'")]

Workaround If I deploy without args, no error occurs. Another workaround is to set command inside spec.container:

...
        env:
        - name: PHPLDAPADMIN_HTTPS
          value: "false"
        - name: PHPLDAPADMIN_LDAP_HOSTS
          value: ldap
        command:
        - /bin/sh
        - ce
        - /container/tool/run

Without such argument I may have some problems with mounted files on some systems (as written in README.md). How can I avoid this problem?

Looks like this is because of broken permissions/ownership on file:

root@ldap:/# ls -la /container/service/:runit/ ls: cannot access '/container/service/:runit/download.sh': No such file or directory total 12 drwxrwxr-x 2 root root 4096 Sep 4 2018 . drwxr-xr-x 1 root root 4096 Jul 11 13:51 .. c????????? ? ? ? ? ? download.sh`
