I am getting following error while trying to run pip.
Could not open requirements file: [Errno 2] No such file or directory: '/home/elasticsearch/text-embeddings/requirements.txt'
The command '/bin/sh -c pip3.6 install -r /home/elasticsearch/text-embeddings/requirements.txt' returned a non-zero code: 1
My dockerfile looks like this...
FROM elasticsearch:7.3.1
RUN yum install -y https://centos7.iuscommunity.org/ius-release.rpm
RUN yum update
RUN yum install -y python36u python36u-libs python36u-devel python36u-pip git
RUN mkdir /home/elasticsearch/
RUN cd /home/elasticsearch/
RUN git clone https://github.com/jtibshirani/text-embeddings.git
WORKDIR /home/elasticsearch/text-embeddings
RUN cd /home/elasticsearch/text-embeddings
RUN pip3.6 install -r /home/elasticsearch/text-embeddings/requirements.txt
CMD ["python3.6", "/home/elasticsearch/text-embeddings/src/main.py"]
I have checked that these commands run successfully on the server if run one command at a time from command-prompt.
Try with the following Dockerfile:
FROM elasticsearch:7.3.1
RUN yum install -y https://centos7.iuscommunity.org/ius-release.rpm
RUN yum update
RUN yum install -y python36u python36u-libs python36u-devel python36u-pip git
RUN mkdir /home/elasticsearch/
WORKDIR /home/elasticsearch/
RUN git clone https://github.com/jtibshirani/text-embeddings.git
RUN pip3.6 install -r /home/elasticsearch/text-embeddings/requirements.txt
CMD ["python3.6", "/home/elasticsearch/text-embeddings/src/main.py"]
The issue with the original Dockerfile is the RUN cd /path. Each build stage executes in a separate container thus cd 'ing to a directory does nothing. For changing active directory during build use WORKDIR instruction.
the file requirements.txt is in /usr/share/elasticsearch/text-embeddings not /home/elasticsearch/text-embeddings
this will work:
FROM elasticsearch:7.3.1
RUN yum install -y https://centos7.iuscommunity.org/ius-release.rpm
RUN yum update
RUN yum install -y python36u python36u-libs python36u-devel python36u-pip git
RUN git clone https://github.com/jtibshirani/text-embeddings.git
WORKDIR /usr/share/elasticsearch/text-embeddings
RUN pip3.6 install -r /usr/share/elasticsearch/text-embeddings/requirements.txt
CMD ["python3.6", "/usr/share/elasticsearch/text-embeddings/src/main.py"]
The issue is due to a combination of a couple of the answers here #leopal is correct whereas the mkdir and cd are run in different layers and don't result in what you're expecting ref. this answer.
FROM elasticsearch:7.3.1
RUN yum install -y https://centos7.iuscommunity.org/ius-release.rpm
RUN yum update
RUN yum install -y python36u python36u-libs python36u-devel python36u-pip git
RUN mkdir /home/elasticsearch/
RUN cd /home/elasticsearch/
RUN git clone https://github.com/jtibshirani/text-embeddings.git
ENTRYPOINT ["bash"]
... running the container (i.e. docker build -t so:57689606 . && docker run --rm -it so:57689606) will drop you in a shell in the /usr/share/elasticsearch directory with all the files present as pointed out by #LinPy here. Adding the WORKDIR after your checkout is moving you to a directory where the repository wasn't cloned (e.g. /home/elasticsearch).
FROM elasticsearch:7.3.1
RUN yum install -y https://centos7.iuscommunity.org/ius-release.rpm
RUN yum update
RUN yum install -y python36u python36u-libs python36u-devel python36u-pip git
RUN mkdir /home/elasticsearch/
RUN cd /home/elasticsearch/
RUN git clone https://github.com/jtibshirani/text-embeddings.git
WORKDIR /home/elasticsearch/text-embeddings
ENTRYPOINT ["bash"]
... will drop you in a shell inside an empty folder when you run the container (hence the [Errno 2] No such file or directory error).
Also, specifying a WORKDIR creates the directory if it doesn't already exist, e.g. your RUN mkdir /home/elasticsearch/ and RUN cd /home/elasticsearch instructions don't work as you'd expect and are merely adding useless layers to your final image. Functional Dockerfile:
FROM elasticsearch:7.3.1
RUN yum install -y https://centos7.iuscommunity.org/ius-release.rpm
RUN yum update
RUN yum install -y python36u python36u-libs python36u-devel python36u-pip git
WORKDIR /home/elasticsearch/
RUN git clone https://github.com/jtibshirani/text-embeddings.git
RUN python3.6 -m pip install -r /home/elasticsearch/text-embeddings/requirements.txt
CMD ["python3.6", "/home/elasticsearch/text-embeddings/src/main.py"]
Finally, removing the unnecessary layers in your final image (optimized Dockerfile):
FROM elasticsearch:7.3.1
RUN yum install -y https://centos7.iuscommunity.org/ius-release.rpm
RUN yum update && \
yum install -y \
python36u \
python36u-libs \
python36u-devel \
python36u-pip \
git && \
yum clean all
WORKDIR /home/elasticsearch/
RUN git clone https://github.com/jtibshirani/text-embeddings.git && \
python3.6 -m pip install -r /home/elasticsearch/text-embeddings/requirements.txt
ENTRYPOINT ["python3.6"]
CMD ["/home/elasticsearch/text-embeddings/src/main.py"]
Note: the apt packages are purposely split on multiple lines, makes it easier to see at a glance what changes in a git diff imo.
Try this command in Dockerfile and try it.
RUN pip install --trusted-host pypi.python.org -r requirements.txt

I am building a container, you can see the docker file, its for rust app deployment on Argonaut. but its not able to start. Here you can see the Dockerfile.
FROM rust:1.64.0-buster AS builder
WORKDIR /app
ARG TOKEN
ARG DATABASE_URL
RUN git config --global url."https://${TOKEN}:#github.com/".insteadOf "https://github.com/"
COPY . .
ENV CARGO_NET_GIT_FETCH_WITH_CLI true
RUN rustup component add rustfmt
RUN apt-get update -y && apt-get install git wget ca-certificates curl gnupg lsb-release cmake libcurl4 -y
RUN cargo build
FROM debian:buster-slim
WORKDIR /app
COPY --from=builder /app/target/debug/linkedin /app/target/release/linkedin
COPY --from=builder /etc/ssl/certs/ca-certificates.crt /etc/ssl/certs/
CMD ["/app/target/release/linkedin"]
EXPOSE 3000
It builds successfully but when it works it gets exit with error code 127.
linkedin-leadr-1 | /app/target/release/linkedin: error while loading shared libraries: libcurl.so.4: cannot open shared object file: No such file or directory
Have not found what's wrong with it, even though I am installing libcurl4. but my docker container is not able to find it. Can you please give me the solution?
As you install libcurl4 in your build environment but not in your execution environment, that's most likely the reason.
There are two ways to solve this:
Install libcurl4 in your final image, or
Link statically by replacing cargo build with
RUN rustup target add x86_64-unknown-linux-musl
RUN cargo build --target=x86_64-unknown-linux-musl --release
The --release flag should get added either way, as I'm sure you don't want to deliver unoptimized debug builds to your enduser ;)
Note that if you choose to install libcurl4 in your final image, you need to clean up the apt cache afterwards, otherwise your image grows immensely:
RUN apt-get update && DEBIAN_FRONTEND=noninteractive apt-get install --yes \
libcurl4 \
&& apt-get clean && rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/*
The full Dockerfile with libcurl4 installed would then look like this:
FROM rust:1.64.0-buster AS builder
WORKDIR /app
ARG TOKEN
ARG DATABASE_URL
RUN git config --global url."https://${TOKEN}:#github.com/".insteadOf "https://github.com/"
COPY . .
ENV CARGO_NET_GIT_FETCH_WITH_CLI true
RUN rustup component add rustfmt
RUN apt-get update -y && apt-get install git wget ca-certificates curl gnupg lsb-release cmake libcurl4 -y
RUN cargo build
# Copy the libcurl shared library from the builder stage into the final container
RUN mkdir -p /usr/local/lib && \
cp /usr/lib/x86_64-linux-gnu/libcurl.so.4 /usr/local/lib && \
ln -s /usr/local/lib/libcurl.so.4 /usr/local/lib/libcurl.so
FROM debian:buster-slim
RUN apt-get update && DEBIAN_FRONTEND=noninteractive apt-get install --yes \
libcurl4 \

How to copy files from dockerfile to host?
(6 answers)
Closed 3 months ago.
I have a simply Dockerfile to build python requirements into a zip file to be uploaded to AWS Lambda.
FROM amazonlinux:2.0.20221004.0
RUN yum install -y python37 && \
yum install -y python3-pip && \
yum install -y zip && \
yum clean all
RUN python3.7 -m pip install --upgrade pip && \
python3.7 -m pip install virtualenv
COPY aws_requirements.txt .
RUN pip install -r aws_requirements.txt -t ./python
RUN zip -r python.zip ./py
Is there a way to copy the python.zip out of the image to the host during the dockerfile?
With buildkit, you can output the result to a directory on the host instead of pushing to a registry. So you can put the zip file in a scratch image and then output that:
FROM amazonlinux:2.0.20221004.0 as build
RUN yum install -y python37 && \
yum install -y python3-pip && \
yum install -y zip && \
yum clean all
RUN python3.7 -m pip install --upgrade pip && \
python3.7 -m pip install virtualenv
COPY aws_requirements.txt .
RUN pip install -r aws_requirements.txt -t ./python
RUN zip -r /python.zip ./py
FROM scratch as artifact
COPY --from=build /python.zip /python.zip
Then running:
docker build --output type=local,dest=out .
Will create a out/python.zip file.
Following is my Dockerfile :-
FROM ubuntu:18.04 AS builder
RUN apt update -y
RUN apt install python3.8 -y && apt install python3-pip -y
RUN apt install build-essential automake pkg-config libtool libffi-dev libgmp-dev -y
RUN apt install libsecp256k1-dev -y
RUN apt install openjdk-8-jre -y
RUN apt install git -y
RUN apt install libkrb5-dev -y
RUN apt install vim -y
RUN mkdir /opt/app
RUN chown -R root:root /opt/app
COPY ["requirements.txt","/opt/app/requirements.txt"]
SHELL ["/bin/bash", "-c"]
WORKDIR /opt/app
RUN pip3 install -r requirements.txt && apt-get -y clean all
RUN mkdir /opt/app/
RUN chown -R root:root /opt/app/
RUN cd /opt/app/
RUN git clone -b master https://bitbucket.org/heroes/test.git
CMD ["bash","/opt/app/bin/connect.sh"]
Docker image is generating with an image file size of 1.7G. I need to have OpenJDK hence cannot use a standard python package as a base package. When I perform docker history , I can see 2 or 3 layers (installing packages above like Python3.8, OpenJDK and libsecp256k1-dev) taking up to 400MB to 500MB in size. Ubuntu as a base image takes only 64 MB however rest of size is taking by my dockerfile layers.
I believe I need to re-write the dockerfile in order to reduce the file size which I did but nothing happened concrete.
Please assist me on reducing the image less than 1 GB at least.
[Update]
Below is my updated Dockerfile:-
FROM ubuntu:18.04 AS builder
WORKDIR /opt/app
COPY requirements.txt /opt/app/aws/requirements.txt
RUN mkdir -p /opt/app/aws \
&& apt-get update -yq \
&& apt-get install -y python3.8 python3-pip openjdk-8-jre -yq && apt-get -y clean all \
&& chown -R root:root /opt/app && cd /opt/app/aws && pip3 install -r requirements.txt
FROM alpine
COPY --from=builder /opt/app /opt/app
SHELL ["/bin/bash", "-c"]
CMD ["bash","/opt/app/aws/bin/connector/connect.sh"]
Screenshot of image size:-
After removing unwanted libraries like git, etc and using the multi-stage build, the image is now approx 1.7 GB which I believe is a lot. Any suggestion to improve this?
You have multiple issues going on.
First, each of your RUN apt install is increasing your image size, you should have them all in the same RUN stage, and at the end of the stage, delete all cached apt files.
Second, you're installing unnecessary stuff. Why would you need vim and git for instance? Why are you installing build-essential and other build-related stuff if you're not building anything?
Third, it seems you tried to do a multi-stage build but ended up adding everything to the same image. Read up on python multi-stage builds.
If we consider best practices instead of multiple RUN use single RUN.
For example
RUN apt-get update -yq \
&& apt-get install -y python3-dev build-essential -yq \
&& apt-get install curl -yq \
&& pip install -r requirements.txt \
&& apt-get purge -y --auto-remove gcc python3-dev build-essential
you can use multistage builds if you don't require git in your final image you can remove in final stage
Also if possible you can use alpine version also.
Try disabling recommended packages of APT with --no-install-recommends, you can read more about it from here.
Now the image is smaller:
FROM ubuntu:18.04 AS builder
RUN apt update -y
RUN apt install python3-pip -y
RUN apt install build-essential automake pkg-config libtool libffi-dev libgmp-dev -y
RUN apt install libsecp256k1-dev -y
RUN apt install openjdk-8-jre-headless -y
RUN apt install git -y
RUN apt install libkrb5-dev -y
RUN apt install vim -y
RUN mkdir /opt/app
RUN chown -R root:root /opt/app
COPY ["requirements.txt","/opt/app/requirements.txt"]
SHELL ["/bin/bash", "-c"]
WORKDIR /opt/app
RUN pip3 install -r requirements.txt && apt-get -y clean all
RUN mkdir /opt/app/
RUN chown -R root:root /opt/app/
RUN cd /opt/app/
RUN git clone -b master https://bitbucket.org/heroes/test.git
CMD ["bash","/opt/app/bin/connect.sh"]
I would like to have sbt in my docker image. I created a Dockerfile base on centos:centos8 image:
FROM centos:centos8
ENV SCALA_VERSION 2.13.1
ENV SBT_VERSION 0.13.18
RUN yum install -y epel-release
RUN yum update -y && yum install -y wget
RUN wget -O /usr/local/bin/sbt-launch.jar http://repo.typesafe.com/typesafe/ivy-releases/org.scala-sbt/sbt-launch/$SBT_VERSION/sbt-launch.jar
WORKDIR /root
EXPOSE 8080
RUN sbt compile
CMD sbt run
And also I need to have sbt installed here, but when I ran this script I got an error:
Step 10/11 : RUN sbt compile
---> Running in 0aadcd774ba0
/bin/sh: sbt: command not found
I cannot understand why sbt could not been found. Is it a good way to achieve what I need or I should try other one? But I need to do it with centos
EDIT:
Finally it works after help from answer below. Working script looks like:
FROM centos:centos8
ENV SBT_VERSION 0.13.17
RUN yum install -y java-11-openjdk && \
yum install -y epel-release && \
yum update -y && yum install -y wget && \
wget http://dl.bintray.com/sbt/rpm/sbt-$SBT_VERSION.rpm && \
yum install -y sbt-$SBT_VERSION.rpm
WORKDIR /root
EXPOSE 8080
RUN sbt compile
CMD sbt run
You would need to install sbt inside your Dockerfile. Here is an example:
FROM centos:centos8
ENV SCALA_VERSION 2.13.1
ENV SBT_VERSION 0.13.17
RUN yum install -y epel-release
RUN yum update -y && yum install -y wget
# INSTALL JAVA
RUN yum install -y java-11-openjdk
# INSTALL SBT
RUN wget http://dl.bintray.com/sbt/rpm/sbt-${SBT_VERSION}.rpm
RUN yum install -y sbt-${SBT_VERSION}.rpm
RUN wget -O /usr/local/bin/sbt-launch.jar http://repo.typesafe.com/typesafe/ivy-releases/org.scala-sbt/sbt-launch/$SBT_VERSION/sbt-launch.jar
WORKDIR /root
EXPOSE 8080
RUN sbt compile
CMD sbt run
Note: I did not see the version you had in your env variable (0.13.18) so I changed it to 0.13.17.
I ran into an issue where bintray.com was returning 403 randomly. I'm assuming it might be some kind of traffic throttle. Added the rpm file locally.
COPY sbt-0.13.18.rpm /
RUN yum install -y sbt-0.13.18.rpm
I have the below Dockerfile.

While building image it failed in step 23 i.e.
RUN mvn clean package -Pspark-1.6 -Phadoop-2.6 -DskipTests
Now when I rebuild it starts to build from step 23 as docker is using cache.
But if I want to rebuild the image from step 21 i.e.
RUN git clone https://github.com/apache/incubator-zeppelin.git
How can I do that?
Is deleting the cached image is the only option?
Is there any additional parameter to do that?
You can rebuild the entire thing without using the cache by doing a
docker build --no-cache -t user/image-name
To force a rerun starting at a specific line, you can pass an arg that is otherwise unused. Docker passes ARG values as environment variables to your RUN command, so changing an ARG is a change to the command which breaks the cache. It's not even necessary to define it yourself on the RUN line.

And then just run it with a unique arg:
docker build --build-arg INCUBATOR_VER=20160613.2 -t user/image-name .
To change the argument with every build, you can pass a timestamp as the arg:
docker build --build-arg INCUBATOR_VER=$(date +%Y%m%d-%H%M%S) -t user/image-name .
or:
docker build --build-arg INCUBATOR_VER=$(date +%s) -t user/image-name .
As an aside, I'd recommend the following changes to keep your layers smaller, the more you can merge the cleanup and delete steps on a single RUN command after the download and install, the smaller your final image will be. Otherwise your layers will include all the intermediate steps between the download and cleanup:

One workaround:
Locate the step you want to execute from.
Before that step put a simple dummy operation like "RUN pwd"
Then just build your Dockerfile. It will take everything up to that step from the cache and then execute the lines after the dummy command.
To complete Dmitry's answer, you can use uniq arg like date +%s to keep always same commanline
docker build --build-arg DUMMY=`date +%s` -t me/myapp:1.0.0
Dockerfile:
...
ARG DUMMY=unknown
RUN DUMMY=${DUMMY} git clone xxx
...
A simpler technique.
Dockerfile:Add this line where you want the caching to start being skipped.
COPY marker /dev/null
Then build using
date > marker && docker build .
Another option is to delete the cached intermediate image you want to rebuild.
Find the hash of the intermediate image you wish to rebuild in your build output:
Step 27/42 : RUN lolarun.sh
---> Using cache
---> 328dfe03e436
Then delete that image:
$ docker image rmi 328dfe03e436
Or if it gives you an error and you're okay with forcing it:
$ docker image rmi -f 328dfe03e436
Finally, rerun your build command, and it will need to restart from that point because it's not in the cache.
If place ARG INCUBATOR_VER=unknown at top, then cache will not be used in case of change of INCUBATOR_VER from command line (just tested the build).
For me worked:
# The rebuild starts from here
ARG INCUBATOR_VER=unknown
RUN INCUBATOR_VER=${INCUBATOR_VER} git clone https://github.com/apache/incubator-zeppelin.git
As there is no official way to do this, the most simple way is to temporarily change the specific RUN command to include something harmless like echo:
RUN echo && apt-get -qq update && \
apt-get install nano
After building remove it.
