Taking snapshot in Openshift elasticsearch

[afwsl2003 (A.F.Wahab)]

Hi,

I'm trying to create a repository to take snapshot (https://www.elastic.co/guide/en/elasticsearch/reference/2.4/modules-snapshots.html)

When I execute the curl PUT command to create the repository I'm getting repository_missing_exception error. Could anyone please help why I'm getting repository_missing_exception when I'm actually trying to create the repository. Thank you.

I have very little knowledge in ES, so please bear with me if I have done something incorrectly.

Following is the command I tried.

sh-4.2$ curl --key /etc/elasticsearch/secret/admin-key --cert /etc/elasticsearch/secret/admin-cert --cacert /etc/elasticsearch/secret/admin-ca PUT https://localhost:9200/_snapshot/my_backup{"type":"fs","settings":{"location":"/elasticsearch/persistent/backup_test","compress":true}}

I'm not sure about the curl command syntax.
curl: (6) Could not resolve host: PUT - that suggests to me that you're not talking to the host localhost but to PUT.

I would try:

curl --key /etc/elasticsearch/secret/admin-key \
    --cert /etc/elasticsearch/secret/admin-cert \
    --cacert /etc/elasticsearch/secret/admin-ca \
    https://localhost:9200/_cat/health?v

Which can be shortened to:

es_util --query=_cat/health?v

If that helps, then the curl you want might be something like this:

curl --key /etc/elasticsearch/secret/admin-key \
    --cert /etc/elasticsearch/secret/admin-cert \
    --cacert /etc/elasticsearch/secret/admin-ca \
    -XPUT https://localhost:9200/_snapshot/my_backup \
    -d '{"type":"fs","settings":{"location":"/elasticsearch/persistent/backup_test","compress":true}}'

Shortened to:

es_util --query=_snapshot/my_backup -XPUT \
    -d '{"type":"fs","settings":{"location":"/elasticsearch/persistent/backup_test","compress":true}}'
