Hi, We are using elasticsearch in a Docker container with one node . We want to use memlock parameter as true. But when we set  
bootstrap.memory\_lock: true in elasticsearch.yml file we received ;

**ERROR: [1] bootstrap checks failed**  
**[1]: memory locking requested for elasticsearch process but memory is not locked**

* * *

_ **Here elasticsearch.yml file ;** _

http.host: 0.0.0.0

transport.host: 0.0.0.0  
#discovery.zen.minimum\_master\_nodes: 1

bootstrap.memory\_lock: true

## #index.refresh\_interval: 30s #index.translog.flush\_threshold\_ops: 50000

Here [docker-entrypoint.sh](http://docker-entrypoint.sh);

#!/bin/bash

set -e  
if ["${1:0:1}" = '-']; then  
set -- elasticsearch "$@"  
fi

if ["$1" = 'elasticsearch' -a "$(id -u)" = '0']; then  
# Change the ownership of user-mutable directories to elasticsearch  
for path in   
/usr/share/elasticsearch/data   
/usr/share/elasticsearch/logs   
; do  
chown -R elasticsearch:elasticsearch "$path"  
done

```
set -- gosu elasticsearch "$@"
#exec gosu elasticsearch "$BASH_SOURCE" "$@"

```

## fi exec "$@"

Could you please help us?

There is too many configuration suggestion on the web. We try some of them but couldn't find a exact solution.

The last we try to set this parameters with [entrypoint.sh](http://entrypoint.sh) in container;

echo "LimitMEMLOCK=infinity" \>\> /usr/lib/systemd/system/elasticsearch.service  
echo "MAX\_LOCKED\_MEMORY=unlimited" \>\> /etc/init.d/elasticsearch  
echo "elasticsearch soft memlock unlimited" \>\> /etc/security/limits.conf  
echo "elasticsearch hard memlock unlimited" \>\> /etc/security/limits.conf

But the error continues.
