When I try to send email inside Docker container it displays this messages, but I never received email.
root#a036e48556e1:/# mail -s "Test docker, sendmail" erros#mydomain.com < /dev/null
mail: Null message body; hope that's ok
I simply need receive email if Cron task fails. Does Anyone have idea how to do It?

I am new to docker and not an IT-specialist. I try to install Kartoza Geoserver in Docker on Heroku, but so far no success. Does anyone has experience with this and can explain me the settings in the dockerfile and the steps specifically for a Heroku install?
So far I tried a build with a modified dockerfile but I always get the same error (in the log trail) when opening/launching geoserver on Heroku:
"Error: groupadd: cannot open /etc/group".
I guess it is an permission/privileges issue.
Any sharing of experience on modifying the docker file so that the image is read by Heroku would be helpfull.
Modifying the settings in the dockerfile:
Removed the port forwarding from dockerfile
Add RUN adduser -D myuser USER myuser to dockerfile
Result dockerfile:

Then build it with argument --platform linux/amd64 (I use arm64 architecture). Then pushed it to Heroku. All the time I get the same error.
I want to create a minimal docker image.
For that purpose I am using the following multi-stage build dockerfile.
FROM python:3.9-slim as base
ENV LANG=C.UTF-8 \
LC_ALL=C.UTF-8 \
PYTHONDONTWRITEBYTECODE=1 \
PYTHONFAULTHANDLER=1 \
PYTHONHASHSEED=random \
PYTHONUNBUFFERED=1
WORKDIR /app
FROM base as builder
ENV PIP_DEFAULT_TIMEOUT=100 \
PIP_DISABLE_PIP_VERSION_CHECK=1 \
PIP_NO_CACHE_DIR=1 \
POETRY_VERSION=1.1.13
COPY pyproject.toml poetry.lock ./
RUN apt-get update && \
apt-get install make build-essential libssl-dev zlib1g-dev \
libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm \
libncursesw5-dev xz-utils tk-dev libxml2-dev libxmlsec1-dev \
libffi-dev liblzma-dev python3.9-venv --yes && \
pip install "poetry==$POETRY_VERSION" && \
python -m venv /venv && \
poetry export -f requirements.txt | /venv/bin/pip install -r /dev/stdin
COPY . /app
RUN poetry build && /venv/bin/pip install dist/*.whl
FROM base as final
ENV PATH=/venv/bin:$PATH
COPY --from=builder /venv /venv
RUN apt-get update && apt-get install -y procps curl
# for prometheus
EXPOSE 9090
CMD ["my_command"]
However, no matter where I put the final install command in the final stage the commands are not found in the final image.
RUN apt-get update && apt-get install -y procps curl
I have tried putting it before and after the COPY and ENV and still nothing...
Finally, I added another stage between base and builder just to run this command and then everything works fine.
It's bugging me why this would be the case though. Any ideas what's wrong with the dockerfile above?
Docker image is built but when I want to run it, it shows this error:
Error: Unable to access jarfile rest-service-1.0.jar
My OS is Ubuntu 18.04.1 LTS and I use docker build -t doc-service & docker run doc-service.
This is my Dockerfile:

Can anyone help me on this?
Based on the comments, you must add the JAR when building the image by defining in your Dockerfile :
COPY rest-service-1.0.jar /document-service/rest-service-1.0.jar
You could also just use :
COPY rest-service-1.0.jar /rest-service-1.0.jar
, and remove cd /document-service in your entrypoint script, as on ubuntu:16.04 images, default working directory is /. My opinion is that setting the working directory in the script is safer, so you should just go for the first solution.
Note that you could also use ADD instead of COPY (as you already did in your Dockerfile), but here only COPY is necessary (read this post if you want more info : What is the difference between the `COPY` and `ADD` commands in a Dockerfile?).
Finally, I suggest you to add the COPY line at the end of your Dockerfile, so that if a new JAR is built, image won't be rebuilt from scratch but from an existing layer, speeding up build time.
it looking error about workdir
you must select workdir for this copy format
try WORKDIR /yourpath/

I have create a apache server in docker, but the ip what i get in access log is just from my docker ip, not from remote client ip.
Is it possible to get remote ip?
I have try to use mod_remoteip and it is not works.
