# Ozone in a Single Container
|
|
|
|
The easiest way to start up an all-in-one ozone container is to use the latest
|
|
docker image from docker hub:
|
|
|
|
```bash
|
|
docker run -p 9878:9878 -p 9876:9876 apache/ozone
|
|
```
|
|
This command will pull down the ozone image from docker hub and start all
|
|
ozone services in a single container. <br>
|
|
This container will run the required metadata servers (Ozone Manager, Storage
|
|
Container Manager) one data node and the S3 compatible REST server
|
|
(S3 Gateway).
|
|
|
|
# Local multi-container cluster
|
|
|
|
If you would like to use a more realistic pseudo-cluster where each components
|
|
run in own containers, you can start it with a docker-compose file.
|
|
|
|
We have shipped a docker-compose and an enviorment file as part of the
|
|
container image that is uploaded to docker hub.
|
|
|
|
The following commands can be used to extract these files from the image in the docker hub.
|
|
```bash
|
|
docker run apache/ozone cat docker-compose.yaml > docker-compose.yaml
|
|
docker run apache/ozone cat docker-config > docker-config
|
|
```
|
|
|
|
Now you can start the cluster with docker-compose:
|
|
|
|
```bash
|
|
docker-compose up -d
|
|
```
|
|
|
|
If you need multiple datanodes, we can just scale it up:
|
|
|
|
```bash
|
|
docker-compose scale datanode=3
|
|
```
|
|
# Running S3 Clients
|
|
|
|
Once the cluster is booted up and ready, you can verify its status by
|
|
connecting to the SCM's UI at [http://localhost:9876](http://localhost:9876).
|
|
|
|
The S3 gateway endpoint will be exposed at port 9878. You can use Ozone's S3
|
|
support as if you are working against the real S3.
|
|
|
|
|
|
Here is how you create buckets from command line:
|
|
|
|
```bash
|
|
aws s3api --endpoint http://localhost:9878/ create-bucket --bucket=bucket1
|
|
```
|
|
|
|
Only notable difference in the above command line is the fact that you have
|
|
to tell the _endpoint_ address to the aws s3api command.
|
|
|
|
Now let us put a simple file into the S3 Bucket hosted by Ozone. We will
|
|
start by creating a temporary file that we can upload to Ozone via S3 support.
|
|
```bash
|
|
ls -1 > /tmp/testfile
|
|
```
|
|
This command creates a temporary file that
|
|
we can upload to Ozone. The next command actually uploads to Ozone's S3
|
|
bucket using the standard aws s3 command line interface.
|
|
|
|
```bash
|
|
aws s3 --endpoint http://localhost:9878 cp --storage-class REDUCED_REDUNDANCY /tmp/testfile s3://bucket1/testfile
|
|
```
|
|
<div class="alert alert-info" role="alert">
|
|
Note: REDUCED_REDUNDANCY is required for the single container ozone, since it
|
|
has a single datanode. </div>
|
|
We can now verify that file got uploaded by running the list command against
|
|
our bucket.
|
|
|
|
```bash
|
|
aws s3 --endpoint http://localhost:9878 ls s3://bucket1/testfile
|
|
```
|
|
|
|
<div class="alert alert-info" role="alert"> You can also check the internal
|
|
bucket browser supported by Ozone S3 interface by clicking on the below link.
