You are using pip version 8.1.1, however version 10.0.0 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
The command '/bin/sh -c pip install --upgrade pip' returned a non-zero code: 1

So I have a test.py file that creates a dataframe and outputs a csv:
from pyspark.sql import SparkSession
spark = SparkSession.builder.getOrCreate()
df = spark.createDataFrame([[1,2],[3,4]])
df.write.csv("test", header=True)
I'm trying to get this to run via Docker but with zero luck.
I created the following Dockerfile:
FROM apache/spark-py:v3.3.0
COPY test.py test.py
# RUN python -m pip install --upgrade pip && pip3 install pyspark==3.3.0
RUN apt-get update -y &&\
apt-get install -y python3 &&\
pip3 install pyspark==3.3.0
CMD ["python3", "test.py"]
and run the following to run the test.py script in Docker:
docker build -t ch_image --rm . && docker run --rm --name ch_container ch_image
I'm getting the following error message:

I've tried:

RUN python -m pip install --upgrade pip && pip3 install pyspark==3.3.0
Any help to understand why I'm not able to run the script would be much appreciated.
You got "permission denied" error. Could you please add "USER root" between step 2 and step 4 in your dockerfile as shown below?
FROM apache/spark-py:v3.3.0
COPY test.py test.py

How can I fix this?

I am trying to get the dordoka/tomcat docker image up and running, but I get this error when running docker build:
Cannot add PPA: 'ppa:~webupd8team/ubuntu/y-ppa-manager'.
ERROR: '~webupd8team' user or team does not exist.
The command '/bin/sh -c apt-get update &&
apt-get install -y software-properties-common &&

apt-get update &&

returned a non-zero code: 1
The command that is failing is add-apt-repository -y ppa:webupd8team/ubuntu/y-ppa-manager. This command runs fine outside of docker. The proxy is configured correctly, as far as I can tell. Any ideas?
#mlowry Is there a particular reason why you have to run this as root?
I assume that when you run it as your user you have also the http_proxy exported ?
In this case you could youse --build-args to pass the http_proxy string.
Quick example:
ubuntu#ip-172-31-10-207:~/test$ docker build --build-arg http_proxy=$http_proxy .

Content of Dockerfile is as follow:

How can I avoid this error message?
Try and add RUN apt-get update first.
Once the packages are updated, you can install, for instance, cowsay.
See for instance this Dockerfile as an example of RUN apt-get commands:
FROM debian:jessie
RUN apt-get update && apt-get install -y cowsay
COPY docker.cow /usr/share/cowsay/cows/docker.cow
ENTRYPOINT ["/usr/games/cowsay","-f","docker"]
