You can create and use environment variables in the shell, without needing Python:

    <div class="termy">

    ```console
    // You could create an env var MY_NAME with
    $ export MY_NAME="Wade Wilson"

{{- if .Values.configPathmc }} MC_CONFIG_DIR="{{ .Values.configPathmc }}" MC="/usr/bin/mc --insecure --config-dir ${MC_CONFIG_DIR}" {{- else }} MC="/usr/bin/mc --insecure" {{- end }} # AccessKey and secretkey credentials file are added to prevent shell execution errors caused by special characters. # Special characters for example : ',",<,>,{, MINIO_ACCESSKEY_SECRETKEY_TMP="/tmp/accessKey_and_secretKey_svcacct_tmp" # connectToMinio # Use a check-sleep-check loop to wait for MinIO service to be available...
