Creating Docker Images for Running Kaldi on YARN

How to create docker images to run Kaldi on YARN

Dockerfile to run Kaldi on YARN need two part:

Base libraries which Kaldi depends on

1) OS base image, for example nvidia/cuda:10.0-cudnn7-devel-ubuntu18.04

2) Kaldi depended libraries and packages. For example python, g++, make. For GPU support, need cuda, cudnn, etc.

3) Kaldi compile.

Libraries to access HDFS

1) JDK

2) Hadoop

Here's an example of a base image (w/o GPU support) to install Kaldi:

FROM nvidia/cuda:10.0-cudnn7-devel-ubuntu18.04

RUN apt-get clean && \
    apt-get update && \
    apt-get install -y --no-install-recommends \
        sudo \
        openjdk-8-jdk \
        iputils-ping \
        g++ \
        make \
        automake \
        autoconf \
        bzip2 \
        unzip \
        wget \
        sox \
        libtool \
        git \
        subversion \
        python2.7 \
        python3 \
        zlib1g-dev \
        ca-certificates \
        patch \
        ffmpeg \
        vim && \
        rm -rf /var/lib/apt/lists/* && \
        ln -s /usr/bin/python2.7 /usr/bin/python

RUN git clone --depth 1 https://github.com/kaldi-asr/kaldi.git /opt/kaldi && \
    cd /opt/kaldi && \
    cd /opt/kaldi/tools && \
    ./extras/install_mkl.sh && \
    make -j $(nproc) && \
    cd /opt/kaldi/src && \
    ./configure --shared --use-cuda && \
    make depend -j $(nproc) && \
    make -j $(nproc)

On top of above image, add files, install packages to access HDFS

RUN apt-get update && apt-get install -y openjdk-8-jdk wget
# Install hadoop
ENV HADOOP_VERSION="3.2.1"
ENV JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
RUN wget https://archive.apache.org/dist/hadoop/common/hadoop-${HADOOP_VERSION}/hadoop-${HADOOP_VERSION}.tar.gz && \
    tar zxf hadoop-${HADOOP_VERSION}.tar.gz && \
    ln -s hadoop-${HADOOP_VERSION} hadoop-current && \
    rm hadoop-${HADOOP_VERSION}.tar.gz

Build and push to your own docker registry: Use docker build ... and docker push ... to finish this step.

Use examples to build your own Kaldi docker images

We provided following examples for you to build kaldi docker images.

For latest Kaldi

• *base/ubuntu-18.04/Dockerfile.gpu.kaldi_latest: Latest Kaldi that supports GPU, which is prebuilt to CUDA10, with models.

Build Docker images

Manually build Docker image:

Under docker/ directory,The CLUSTER_NAME can be modified in build-all.sh to have installation permissions, run build-all.sh to build Docker images. It will build following images:

• kaldi-latest-gpu-base:0.0.1 for base Docker image which includes Hadoop, Kaldi, GPU base libraries, which includes thchs30 model.

Use prebuilt images

(No liability) You can also use prebuilt images for convenience in the docker hub:

• hadoopsubmarine/kaldi-latest-gpu-base:0.0.1
