Use Chronos in Container (docker)#

This dockerfile helps user to build a docker image where Chronos-nightly build version is deployed.

Build an image#

First clone the repo BigDL to the local.

git clone https://github.com/intel-analytics/BigDL.git

Then cd to the root directory of BigDL, and copy the Dockerfile to it.

cd BigDL
cp docker/chronos-nightly/Dockerfile ./Dockerfile

Then build your docker image with Dockerfile:

sudo docker build -t chronos-nightly:b1 . # You may choose any NAME:TAG you want.

(Optional) Or build with a proxy:

# typically, you need a proxy for building since there will be some downloading.
sudo docker build \
    --build-arg http_proxy=http://<your_proxy_ip>:<your_proxy_port> \ #optional
    --build-arg https_proxy=http://<your_proxy_ip>:<your_proxy_port> \ #optional
    -t chronos-nightly:b1 . # You may choose any NAME:TAG you want.

According to your network status, this building will cost 15-30 mins.

Tips: When errors happen like E: Package 'apt-utils' has no installation candidate, it’s usually related to the bad network status. Please build with a proxy.

Run the image#

sudo docker run -it --rm --net=host chronos-nightly:b1 bash

Use Chronos#

A conda environment is created for you automatically. bigdl-chronos and all of its depenencies are installed inside this environment.

(chronos) root@cpx-3:/opt/work#

Run unitest examples on Jupyter Notebook for a quick use#

You can run these on Jupyter Notebook on single node server if you pursue a quick use on Chronos.

(chronos) root@cpx-3:/opt/work# cd /opt/work/colab-notebook #Unitest examples are here.

(chronos) root@cpx-3:/opt/work# jupyter notebook --notebook-dir=./ --ip=* --allow-root #Start the Jupyter Notebook services.

After the Jupyter Notebook service is successfully started, you can connect to the Jupyter Notebook service from a browser.

  1. Get the IP address of the container

  2. Launch a browser, and connect to the Jupyter Notebook service with the URL:
    https://container-ip-address:port-number/?token=your-token
    As a result, you will see the Jupyter Notebook opened.

  3. Open one of these .ipynb files, run through the example and learn how to use Chronos to predict time series.

Shut down docker container#

You should shut down the BigDL Docker container after using it.

  1. First, use ctrl+p+q to quit the container when you are still in it.

  2. Then, you can list all the active Docker containers by command line:

sudo docker ps

You will see your docker containers:

CONTAINER ID        IMAGE                                        COMMAND                  CREATED             STATUS              PORTS               NAMES
40de2cdad025        chronos-nightly:b1         "/opt/work/"   3 hours ago         Up 3 hours                              upbeat_al

  1. Shut down the corresponding docker container by its ID:

sudo docker rm -f 40de2cdad025
