Can't backup clickhouse db which in kubernetes

[cool-tiger]

I try to make backup database, which work in docker container from official yandex image. This docker image runs in kubernetes cluster. I made separate pod with docker image alexakulov/clickhouse-backup and tried to make backup. And i had this error when i started this util:

2019/09/26 11:08:49 envconfig.Process: assigning CLICKHOUSE_CLICKHOUSE_PORT to Port: converting 'tcp://192.168.186.165:9000' to type uint. details: strconv.ParseUint: parsing "tcp://192.168.186.165:9000": invalid syntax

My config:
clickhouse:
  username: default
  password: ""
  host: clickhouse #this is address of host with clickhouse server db
  port: 9000
  data_path: ""
  skip_tables:
  - system.*

  secret_key: ""
  bucket: ""

run this command:
clickhouse-backup create my_backup

Hello!
CLICKHOUSE_CLICKHOUSE_PORT is defined as "tcp://192.168.186.165:9000" it's wrong.
If you want to use "tcp://192.168.186.165:9000" for connecting to clickhouse you must define CLICKHOUSE_HOST="192.168.186.165" and CLICKHOUSE_PORT=9000 (by default)

Thank you, it's work. Perphap variable CLICKHOUSE_HOST are wrong define in container.

By the way I also see that. I do not define that variable manually, so what should I do?

OK I see the reason: It seems to be injected by kubernetes automatically along with many other variables. Thus defining it manually works.
