I am trying to run docker commands from inside my container, but I always get the response "bash: docker: command not found". I've built my image successfully, and run it by trying the following two ways: docker run -it ubuntu bash and docker run -it ubuntu. All is good running the image, however when I try to execute a shell script by doing the following: docker exec ubuntu /path/to/script.sh, I receive the "command not found" error. Here is my Dockerfile:

The docker docs say what I am doing should work. What gives?

I am new to dokers. I need jenkins and jupyter notebook in the same container. I have written the following Dockerfile but I can't access localhost:8888 or 8080 or 50000 when I run this image. However, these ports work very well when I run the official jenkins image. So, I don't know where I am making the mistake in my Dockerfile.

I am trying to run this below command inside a docker container
(centos 7 as the base image)
ssh-keygen -t rsa -N ""
and I get this error:
ssh-keygen: command not found
And this is the Dockerfile I used to build the container
FROM centos:7
ENV VER "0.12.9"
RUN yum update -y && yum install wget -y && yum install unzip -y
RUN yum install epel-release -y && yum install ansible -y
RUN wget https://releases.hashicorp.com/terraform/${VER}/terraform_${VER}_linux_amd64.zip
RUN unzip terraform_${VER}_linux_amd64.zip
RUN mv terraform /usr/local/bin/
RUN rm -rf terraform_${VER}_linux_amd64.zip
Can someone help me, Please?
ssh-keygen is command provided by OpenSSH, you need to install it.
Add yum install openssh-clients -y to your Dockerfile.

I just made a very simple Docker file in my terminal, basically I did the following:
mkdir pgrouted
cd pgrouted
touch Dockerfile
Now I open the Docker file in the nano editor, and I add the following commands to the Docker file:

The entire Dockerfile can be see HERE at a glance.
Now when I try to build the Dockerfile, like so:
docker build -t gautam/pgrouted:v1 .
The Dockerfile runs and then I get the below error:
Step 4 : RUN sudo apt-add-repository -y ppa:ubuntugis/ppa
---> Running in c93c3c5fd5e8
sudo: apt-add-repository: command not found
The command '/bin/sh -c sudo apt-add-repository -y ppa:ubuntugis/ppa' returned a non-zero code: 1
Why am I getting this error?
apt-add-repository is just not in the base Ubuntu image. You'll first need to install it. try apt-get install software-properties-common
By the way, you don't need to use sudo in the Dockerfile because the commands run as root by default unless you change to another user with the USER command.
Add these lines before running apt-add-repository command
RUN apt-get update && \
apt-get install -y software-properties-common && \
rm -rf /var/lib/apt/lists/*
thats worked for me:
RUN apt-get update --fix-missing && \
apt-get install -y software-properties-common && \
rm -rf /var/lib/apt/lists/* && \
add-apt-repository ppa:ondrej/php && \

I installed Elasticsearch in my image based on ubuntu:16.04.
And start the service using
RUN service elasticsearch start
but, it was not started.
If I go into the container and run it, it starts.
I want to run the service and dump the index when I create the image, below is a part of my Dockerfile.
How do I start Elasticsearch in the Dockerfile?
#install OpenJDK-8
RUN apt-get update && apt-get install -y openjdk-8-jdk && apt-get install -y ant && apt-get clean
RUN apt-get update && apt-get install -y ca-certificates-java && apt-get clean
RUN update-ca-certificates -f
ENV JAVA_HOME /usr/lib/jvm/java-8-openjdk-amd64/
RUN export JAVA_HOME
#download ES
RUN wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | apt-key add -
RUN apt-get install -y apt-transport-https
RUN echo "deb https://artifacts.elastic.co/packages/6.x/apt stable main" | tee -a /etc/apt/sources.list.d/elastic-6.x.list
RUN apt-get update && apt-get install -y elasticsearch
RUN service elasticsearch start
The RUN command executes only during the build phase. It stops after the build is completed. You should use CMD (or ENTRYPOINT) instead:
CMD service elasticsearch start && /bin/bash
It's better wrapping the starting command in your own file and then only execute the file:
CMD /start_elastic.sh
I don't know why not take official oss image, but, this Docker file based on Debian work:
FROM java:8-jre
ENV ES_NAME=elasticsearch \
ELASTICSEARCH_VERSION=6.6.1
ENV ELASTICSEARCH_URL=https://artifacts.elastic.co/downloads/$ES_NAME/$ES_NAME-$ELASTICSEARCH_VERSION.tar.gz
RUN apt-get update && apt-get install -y --assume-yes openssl bash curl wget \
&& mkdir -p /opt \
&& echo '[i] Start create elasticsearch' \
&& wget -T 15 -O /tmp/$ES_NAME-$ELASTICSEARCH_VERSION.tar.gz $ELASTICSEARCH_URL \
&& tar -xzf /tmp/$ES_NAME-$ELASTICSEARCH_VERSION.tar.gz -C /opt/ \
&& ln -s /opt/$ES_NAME-$ELASTICSEARCH_VERSION /opt/$ES_NAME \
&& useradd elastic \
&& mkdir -p /var/lib/elasticsearch /opt/$ES_NAME/plugins /opt/$ES_NAME/config/scripts \
&& chown -R elastic /opt/$ES_NAME-$ELASTICSEARCH_VERSION/
ENV PATH=/opt/elasticsearch/bin:$PATH
USER elastic
CMD [ "/bin/sh", "-c", "/opt/elasticsearch/bin/elasticsearch --E cluster.name=test --E network.host=0 $ELASTIC_CMD_OPTIONS" ]
I believe most of the commands you'll be able to use on Ubuntu.
Don't forget to run sudo sysctl -w vm.max_map_count=262144 on your host
