Kibana in Docker does not show snapshot result

[thesn]

Hi,

I have Elasticsearch 7.11.1 and Kibana 7.11.1 installed using docker with volume bindings below.

      elastic7111:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.11.1
    container_name: elastic7111
    restart: unless-stopped
    ports:
      - 9200:9200
    hostname: elastic7111
    user: elasticsearch
    volumes:
      - "./elastic-config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml:ro"
      - "./elastic-config/jvm.options:/usr/share/elasticsearch/config/jvm.options:ro"
      - "./elastic-config:/usr/share/elasticsearch/config:rw"
      - "./elastic-data:/usr/share/elasticsearch/data:rw"
      - "./elastic-logs:/usr/share/elasticsearch/logs:rw"
      - "./elastic-backup:/usr/share/elasticsearch/backup:rw"
  kibana7111:
    image: "docker.elastic.co/kibana/kibana:7.11.1"
    container_name: kibana7111
    restart: unless-stopped
    ports:
      - "5601:5601"
    mem_limit: 2g
    environment:
      - "LS_JAVA_OPTS=-Xmx2g -Xms1g"
    volumes:
      - "./kibana.yml:/usr/share/kibana/config/kibana.yml:ro"
    depends_on:
      - elastic7111

Here is the elasticsearch.yaml:

    cluster.name: BJBMWDEVQA-CLUSTER
node.name: elastic01

path.data: /usr/share/elasticsearch/data
path.logs: /usr/share/elasticsearch/logs
path.repo: /usr/share/elasticsearch/backup

# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
bootstrap.memory_lock: true

# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
network.host: 0.0.0.0
http.port: 9200
transport.host: localhost

Note that the path.data, path.log, and path.repo all pointing the a location inside the docker container, which then binded in docker-compose volume.

And then I create a repository in Kibana using the Shared File System pointing to that path.repo location.
And then I create a "<daily-{now/d}>" policy, and manually run the policy.

I believe the task executed successfully, because I can see the files in both "elastic-backup" (host) and "/usr/share/elasticsearch/backup" (docker) directory.

sh-4.4$ 

But the resulting snapshot is not available in Kibana Snapshot page.
Questions:

1. Have I configured the docker-compose correctly?
2. Why Kibana shows " You don't have any snapshots yet" in the Snapshot page. It seems like Kibana cannot read the repository location.

Please enlighten me.
Thank you.
