Answer 1

Tabs are not allowed in YML file. You can edit it with any editor nano or vim or vi.

Replacing or editing the elasticsearch.yml file wont leads to data loss.

Docker images are delivered trimmed to bare minimum - so no editor is installed with the shipped container. That's why there's a need to install it manually.

docker exec -it  bash

and run:

apt-get update
apt-get install vim

or use the following Dockerfile:

FROM confluent/postgres-bw:0.1

RUN ["apt-get", "update"]
RUN ["apt-get", "install", "-y", "vim"]
