As we know JMeter is desktop based application which will get launched in our OS and we can use it to do performance testing but what if I want to use it as web application rather than desktop application.
How can I use Jmeter desktop application as web app and expose this on some port ?
I tried following but none of them launched Jmeter as webapp.
Converting the jmeter desktop application to webapp using webswing, java web start but was not successful in that.
Running the jmeter jar directly in rest controller to launch it as webapp but it did not launch as webapp.
Also tried to run the jmeter docker image but that also did not help.
Can anyone please tell me ? do we have web app of jmeter or web version of jmeter so that I can use it as webapp and access it from web browser via some port ? like this localhost:8080/jmeter
Currently running JMeter as a "pure" web application is not possible, however if all you need to do is to make JMeter GUI available to yourself or someone else via a web interface/browser you can install JMeter into a Docker container and expose the virtual desktop via i.e. noVNC so you (or someone else) will be able to open specific hostname/port in the browser and see JMeter GUI and create, edit or debug a script.
Example Dockerfile:
FROM uphy/novnc-alpine
RUN \
apk add --no-cache curl openjdk8-jre bash \
&& curl -L https://archive.apache.org/dist/jmeter/binaries/apache-jmeter-5.4.1.tgz > /tmp/jmeter.tgz \
&& mkdir -p /opt \
&& tar -xvf /tmp/jmeter.tgz -C /opt \
&& rm /tmp/jmeter.tgz \
&& cd /etc/supervisor/conf.d \
&& echo '[program:jmeter]' >> supervisord.conf \
&& echo 'command=/opt/apache-jmeter-5.4.1/bin/./jmeter' >> supervisord.conf \
&& echo 'autorestart=true' >> supervisord.conf
So given you follow next steps:
Build the image:
docker build -t jmeter .
Run the image as the container:
docker run -it --rm -p 8080:8080 jmeter
Open http://localhost:8080/vnc.html URL in your browser (must be Websocket-capable)
You will see a virtual desktop with JMeter

I am running Jmeter in noVNC, able to run Jmeter in noVNC but offcourse in default small window.
But when I create Http(s) script recorder and when click on Start button, I get this error
error is -> "Could not create script recorder -see log for details: >> keytool error: java.security.ProviderException: Could not initialize NSS << command failed code:1
'keytool -genkeypair -alias:root_ca: -dname"CN=_Jmeter Root CA for recording(INSTALL ONLY IF IT IS YOURS).......FULL ERROR in SCREENSHOT"'"
Tried creating Http(s) script recrorder with and without PRoxy setup in my Chrome browser, getting same error.
right hand side of screenshot
below is my Dockerfile
FROM uphy/novnc-alpine
RUN \
apk add --no-cache curl openjdk8-jre bash \
&& apk add --no-cache nss \
&& curl -L https://archive.apache.org/dist/jmeter/binaries/apache-jmeter-5.4.1.tgz > /tmp/jmeter.tgz \
&& mkdir -p /opt \
&& tar -xvf /tmp/jmeter.tgz -C /opt \
&& rm /tmp/jmeter.tgz \
&& cd /etc/supervisor/conf.d \
&& echo '[program:jmeter]' >> supervisord.conf \
&& echo 'command=/opt/apache-jmeter-5.4.1/bin/./jmeter' >> supervisord.conf \
&& echo 'autorestart=true' >> supervisord.conf
ENV JAVA_HOME /usr/lib/jvm/java-1.8-openjdk/
RUN export JAVA_HOME
This is how I am running (related to Use Jmeter desktop application as web app)
creating docker image with noVNC and running Jmeter inside noVNC (dockerfile also provided in the end)
exposing it to some port and accessing it in browser
docker build -t jmeter .
docker run -it --rm -p 8080:8080 jmeter
I checked my docker container also, able to see JDK, jdk is already present here -> /usr/lib/jvm/java-1.8-openjdk/ and jmeter is present here /opt/apache-jmeter-5.4.1
I am not sure should I pass more options or arguments inside docker run command.
I am wondering, how this jmeter will create the certificate inside my bin directory on click of start button, since this Jmeter is running inside noVNC docker ?
Any other way by which we can automatically integrate/create this certificate without importing or without clicking on start button.
How Proxy setting can be done if Jmeter in running inside noVNC container.
I think you need to install nss package
change this line:
apk add --no-cache curl openjdk8-jre bash \
to this one:
apk add --no-cache curl openjdk8-jre bash nss \
Once you re-build the image the HTTP(S) Test Script Recorder should launch normally.
With regards to the certificate, it will be stored in JMeter's "bin" folder in the container so if you want to use in in the browser in the container - you will have to install the browser there as well.
If you want to use the browser on your local machine - you will need to copy the certificate from the container and to expose another port for JMeter's HTTP(S) test script recorder.
Just in case be aware that you can also record JMeter test scripts using JMeter Chrome Extension, in this case you won't have to worry about proxies, certificates and ports.
I have deployed jmeter in kubernetes by using
https://github.com/kubernauts/jmeter-kubernetes
But I am facing difficulties when I want to integrate selenium webdriver with jmeter. I am able to install selenium packages within the docker using
RUN cd /jmeter/apache-jmeter-$JMETER_VERSION/ && wget -q -O /tmp/jpgc-webdriver-3.3.zip https://jmeter-plugins.org/files/packages/jpgc-webdriver-3.3.zip && unzip -n /tmp/jpgc-webdriver-3.3.zip && rm /tmp/jpgc-webdriver-3.3.zip
But how to install chromedriver within docker. There is no official documentation for jmeter on this and I am new to jmeter. I really appreciate if anyone would guide me on this.
There is no official documentation for JMeter because JMeter doesn't support Selenium
You should look into official documentation for Chromedriver and Docker
Given you were able to come up with RUN directive to download and unpack WebDriver Sampler plugin you should be able to do the same with the Chromedriver, like:
RUN wget -q -O /tmp/chromedriver.zip https://chromedriver.storage.googleapis.com/87.0.4280.20/chromedriver_linux64.zip && unzip /tmp/chromedriver.zip && rm /tmp/chromedriver.zip && mv chromedriver/tmp
You will also need to change the ENTRYPOINT to set webdriver.chrome.driver JMeter system property like -Dwebdriver.chrome.driver=/tmp/chromedriver
I want to run vscode in docker for internal test, i've created the following
FROM debian:stable
RUN apt-get update && apt-get install -y apt-transport-https curl gpg
RUN curl https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > microsoft.gpg \
&& install -o root -g root -m 644 microsoft.gpg /etc/apt/trusted.gpg.d/ \
&& echo "deb [arch=amd64] https://packages.microsoft.com/repos/vscode stable main" > /etc/apt/sources.list.d/vscode.list
RUN apt-get update && apt-get install -y code libx11-xcb-dev libasound2
RUN code --user-data-dir="~/.vscode-root"
I use to build
docker build -t vscode .
I use to run
docker run vscode code -v
when I run it like this I got error
You are trying to start vscode as a super user which is not recommended. If you really want to, you must specify an alternate user data directory using the --user-data-dir argument.
I just want to verify it by running something like RUN code -v how can I do it ?
should I change the user ? I just want to run vscode in docker and use some vscode apis
Have you tried using VSCode's built in functionality for developing in a container?
Checkout this page which describes how to do this:
Developing inside a Container
You can try out some of the sample container configurations provided by VSCode and use any of those devcontainer.json files as an example to configure a custom development container to your liking. According to the page above:
Workspace files are mounted from the local file system or copied or cloned into the container. Extensions are installed and run inside the container, where they have full access to the tools, platform, and file system. This means that you can seamlessly switch your entire development environment just by connecting to a different container.
This is a very handy way to have different environments for development that are isolated within the container.
The question is most clear,
How to start complete desktop environment (KDE, XFCE, Gnome doesn't matter) in the Docker remote container.
I were digging over the internet and there are lots of questions about the related topic, but not the same, they all about how to run GUI application not the full desktop.
What I found out:
Necessary run Xvfb
Somehow run e.g. Xfce in that FrameBuffer
Allow x11vnc to share that running X environment
But I'm stuck here actually, always getting whatever errors:
... (EE) Invalid screen configuration 1024x768 for -screen 0
... Cannot open /dev/tty0 (No such file or directory)
Could you give some Dockerfile lines in order reach the goal?
That is I was looking for, the simplest form of the desktop in Docker:
FROM ubuntu
RUN apt-get update
RUN apt-get install xfce4 -y
RUN apt-get install xfce4-goodies -y
RUN apt-get purge -y pm-utils xscreensaver*
RUN apt-get install wget -y
EXPOSE 5901
RUN wget -qO- https://dl.bintray.com/tigervnc/stable/tigervnc-1.8.0.x86_64.tar.gz | tar xz --strip 1 -C /
RUN mkdir ~/.vnc
RUN echo "123456" | vncpasswd -f >> ~/.vnc/passwd
RUN chmod 600 ~/.vnc/passwd
CMD ["/usr/bin/vncserver", "-fg"]
Unfortunately I could not sort out with x11vnc and xvfb. But TigerVNC turned out much better.
This sample generate container with xfce gui and run vncserver with 123456 password. There is no need to overwrite ~/.vnc/xstartup manually because TigerVNC starts up X server by default!
To run the server:
sudo docker run --rm -dti -p 5901:5901 3ab3e0e7cb
To connect there with vncviewer:
vncviewer -AutoSelect 0 -QualityLevel 9 -CompressLevel 0 192.168.1.100:5901
Also you could not care about screen resolution because by default it will resize to fit your screen:
You may also encounter the issue with ipc_channel_posix (chrome and other browsers will not work properly) to eliminate this run container with memory sharing:
docker run -d --shm-size=2g --privileged -p 5901:5901 image-name
x11docker allows to run desktop environments as well as single GUI applications in docker.
Could you give some Dockerfile lines in order reach the goal?
Example desktop images on docker hub.
x11docker does a lot of setup to keep container isolation and provides some additional options like hardware acceleration or pulseaudio sound. Example:
x11docker --desktop x11docker/lxde
x11docker also supports network setups with SSH, VNC and HTML5
Example for SSH setup with xpra:
read Xenv < <(x11docker --xdummy --display=30 x11docker/lxde pcmanfm)
echo $Xenv && export $Xenv
# replace "start" with "start-desktop" to forward a desktop environment
xpra start :30 --use-display --start-via-proxy=no
From client system, connect with
xpra attach ssh:HOSTNAME:30 # replace HOSTNAME with IP or host name of ssh server
Without x11docker:
A quite short setup using Xephyr as nested X server on host is:
Xephyr :1
docker run -v /tmp/.X11-unix/X1:/tmp/.X11-unix/X1:rw \
-e DISPLAY=:1 \
x11docker/xfce
A short Dockerfile with Xfce desktop:
FROM debian:stretch
ENV DEBIAN_FRONTEND noninteractive
RUN apt-get update && apt-get install -y --no-install-recommends xfce4 dbus-x11
CMD startxfce4
I'm working with Hugo
Trying to run inside a Docker container to allow people to easily manage content.
My first task is to get Hugo running and people able to view the site locally.
Here's my Dockerfile:
FROM alpine:3.3
RUN apk update && apk upgrade && \
apk add --no-cache go bash git openssh && \
mkdir -p /aws && \
apk -Uuv add groff less python py-pip && \
pip install awscli && \
apk --purge -v del py-pip && \
rm /var/cache/apk/* && \
mkdir -p /go/src /go/bin && chmod -R 777 /go
ENV GOPATH /go
ENV PATH /go/bin:$PATH
RUN go get -v github.com/spf13/hugo
RUN git clone http://mygitrepo.com /app
WORKDIR /app
EXPOSE 1313
ENTRYPOINT ["hugo","server"]
I'm checking out the site repo then running Hugo - hugo server
I'm then running this container via:
docker run -d -p 1313:1313 --name app app
Which reports everything is starting OK however when I try to browse locally on localhost:1313 I see nothing.
Any ideas where I'm going wrong?
UPDATE
docker ps gives me:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
9e1f12849044 app "hugo server" 16 minutes ago Up 16 minutes 0.0.0.0:1313->1313/tcp app
And docker logs 9e1 gives me:

Web Server is available at http://localhost:1313/ (bind address 127.0.0.1)
Press Ctrl+C to stop
I had the same problem, but following this tutorial http://ahmedalani.com/post/so-recursive-it-hurts/, says about to use the param --bind from hugo server command.
Adding that param mentioned, and the ip 0.0.0.0 we have --bind=0.0.0.0
It works to me, I think this is a natural behavior from every container taking a localhost for self scope, but if you bind with 0.0.0.0 takes a visible scope to the main host.
This is because Docker is actually running in a VM. You need to navigate to the docker-machine ip instead of localhost.
curl $(docker-machine ip):1313
Delete EXPOSE 1313 in your Dockerfile. Dockerfile reference.
