Elasticsearch with Docker

Kibana Install Docker Ubuntu The URL of the Elasticsearch instance is defined via an environment variable in the Kibana Docker Image, just like the mode for Elasticsearch. However, the actual key of the variable is ELASTICSEARCHHOSTS, which contains all valid characters to use the kubectl command for changing an environment variable in a. I'm trying to install Elasticsearch and Kibana with docker. But unable to fix connection. After using docker-compose up -d it says: Starting.

I had a CoreOS machine and I wanted to move my ELK (elasticsearch,logstash, and kibana) stack to docker. At first I wanted to move all the machines, but then I realized that I was already using UDP port 514 for splunk on the same host so I decided to just move just the elasticsearch and kibana components. This was actually perfect, cause all the components were on the same machine before and were using localhost for communication and I wanted to see how the remote communication works out between some of the components.

CoreOS sysctl configuration

Looking over the Install Elasticsearch with Docker, it looks like they recommend modifying the following sysctl/kernel parameter:

The vm_max_map_count kernel setting needs to be set to at least 262144 for production use. Depending on your platform:

Linux

Kibana Docker Install

The vm_map_max_count setting should be set permanently in /etc/sysctl.conf:

To apply the setting on a live system type:

sysctl -w vm.max_map_count=262144

With CoreOS we can follow the instructions laid out in Tuning sysctl parameters. I basically added the following section to my config:

Then ran the following to apply it to the configuration (now if the host reboots that setting will be there):

And finally ran the following to do it on the fly so I can keep proceeding with the setup:

Creating docker-compose config file

There is actually a pretty good example of the compose file for elasticsearch from the main page here. And the Configuring Kibana on Docker page has a good example of the docker-compose section for the kibana service. So I ended up creating the following file:

Preparing Local Volumes

Since I wanted to change some settings (and keep the elasticsearch data persistent), I ended up with the following directory structure:

And you can see in the docker-compose.yml file I am mounting those files into the containers. One more important thing is to chown the files to UID 1000, this is necessary since when the daemons start inside the containers they run as UID 1000 and need access to those directories/files:

There is a note about that in the main documentation: Configuring Elasticsearch with Docker:

custom_elasticsearch.yml should be readable by uid:gid 1000:1000

Configuration Files for Elasticsearch and Kibana

By default x-pack is installed the docker images provided by elastic.co, so I just disabled those features in the configuration. Here are the configs that I ended up with:

And here is the kibana config:

Docker

I could probably pass those into the command or set environment variables, but I decided to use config files.

Send Logs from Logstash

As I mentioned I just kept the original logstash service, so I modified the config to now forward logs to the new elasticsearch instance:

Then I ran the following to make sure the configuration is okay:

Kibana

And then finally the following to restart the service:

Logstash Docker Compose

BTW if you wanted to you could use a similar configuration for the logstash docker-compose configuration:

We are overriding the command since that will allow the process to start as root and to bind the service to UDP port 514. This is discussed in cannot start syslog listener.

Testing out the Config

After that’s all set, we can just run the following to start both of the containers:

Kibana Docker Install For Windows

Kibana docker install

And to confirm everything is okay, check out the logs:

If you want you can also check out the logs are the containers come up:

Exporting the Visualizations

Kibana Docker Install For Mac

I logged into the original kibana instance and went to Management -> Saved Objects -> Export Everything. And that created an export.json file. Initially when I went to the new kibana instance and imported the file (Management -> Saved Objects -> Import), I saw the following error:

It looks like this was a known issue (Kibana .raw in 5.0.0 alpha3) for Kibana 5.0. Since I had old mappings from the 4.x versions they were called .raw and I needed to change them to .keyword. So I ran this on the file:

Kibana Docker Installation

And then the re-import worked without issues. Don’t forget to refresh your field list (Management -> Index Patterns -> Logstash-* -> Refresh field list) after some data comes in from logstash:
