Hi i am new to Jenkins i have repository i clone it first , then i need to build the image using Dockerfile it also include the requirments.txt. When i run requirments.txt file from my build.sh file it works fine but when i run it through jenkins using pipeline like this :
pipeline {
agent any
stages {
stage('Build') {
steps {
sh 'sudo bash /home/salman/mlops/build.sh'
}
}
}
}
it throw this error:
Step 1/6 : FROM ubuntu:latest

Step 2/6 : RUN apt-get update && apt-get install -y python3-pip python3-dev && cd /usr/local/bin && ln -s /usr/bin/python3 python && pip3 install --upgrade pip

Finished: FAILURE
even i check the path of requirments.txt file its correct but it didn't run from jenkins. This is my Dockerfile:
FROM ubuntu:latest
RUN apt-get update \
&& apt-get install -y python3-pip python3-dev \
&& cd /usr/local/bin \
&& ln -s /usr/bin/python3 python \
&& pip3 install --upgrade pip
WORKDIR mlcode
COPY requirments.txt .
RUN pip install --no-cache-dir -r requirments.txt
CMD ["python3", "/mlcode/code.py"]
and this is my build.sh:
if cat /home/salman/mlops/Mlops/mlcode/code.py | grep sklearn ; then
sudo docker build -t mlcontainer -f /home/salman/mlops/Dockerfile .
elif cat /home/salman/mlops/Mlops/mlcode/code.py | grep keras ; then
sudo docker build -t dlcontainer -f /home/salman/mlops/Dockerfile .
else
echo "Code not found";

So I can't seem to figure this out, but I'm getting error code 127 when running a Dockerfile. What causes this error?
My Dockerfile:
FROM composer as comp
FROM php:7.4-fpm-alpine
COPY --from=comp /usr/bin/composer /usr/bin/composer
COPY ./docker/install-deps.sh /tmp/install-deps.sh
RUN echo $(ls /tmp)
RUN /tmp/install-deps.sh
COPY . /var/www
WORKDIR /var/www
RUN composer install -o --no-dev
The results after building the Dockerfile:

pecl channel-update pecl.php.net
pecl install yaml
docker-php-ext-enable yaml
apk del --purge .build-deps
Docker is executing the install-deps.sh script. The issue is with a command inside install-deps.sh that is not recognized when docker attempts to run the script.
As you can see the script returns an error code of 127 meaning that a command within the file does not exist.
For instance - try this:
touch test.sh
echo "not-a-command" >> test.sh
chmod 755 test.sh
/bin/sh -c "./test.sh"
Output:
/root/test.sh: line 1: not-a-command: command not found
Now check the exit code:
echo $?
127
I would suggest running the script inside an interactive environment to identify/install the command that is not found.
I am having trouble in optimizing my docker build step.
Below is my use case:
In my jenkinsfile I am building 3 docker images.
from *docker/test/Dockerfile*
from *docker/dev/Dockerfile*
stage('Build') {
steps {
sh 'docker build -t Test -f docker/test/Dockerfile .'
sh 'set +x && eval $(/usr/local/bin/aws-login/aws-login.sh $AWS_ACCOUNT jenkins eu-west-2) \
&& docker build -t DEV --build-arg S3_FILE_NAME=environment.dev.ts \
--build-arg CONFIG_S3_BUCKET_URI=s3://bucket \
--build-arg AWS_SESSION_TOKEN=$AWS_SESSION_TOKEN \
--build-arg AWS_DEFAULT_REGION=$AWS_DEFAULT_REGION \
--build-arg AWS_SECRET_ACCESS_KEY=$AWS_SECRET_ACCESS_KEY \
--build-arg AWS_ACCESS_KEY_ID=$AWS_ACCESS_KEY_ID \
-f docker/dev/Dockerfile .'
sh 'set +x && eval $(/usr/local/bin/aws-login/aws-login.sh $AWS_ACCOUNT jenkins eu-west-2) \
&& docker build -t QA --build-arg S3_FILE_NAME=environment.qa.ts \
--build-arg CONFIG_S3_BUCKET_URI=s3://bucket \
--build-arg AWS_SESSION_TOKEN=$AWS_SESSION_TOKEN \
--build-arg AWS_DEFAULT_REGION=$AWS_DEFAULT_REGION \
--build-arg AWS_SECRET_ACCESS_KEY=$AWS_SECRET_ACCESS_KEY \
--build-arg AWS_ACCESS_KEY_ID=$AWS_ACCESS_KEY_ID \
-f docker/dev/Dockerfile .'
}
}
stage('Test') {
steps {
sh 'docker run --rm TEST npm run test'
}
}
Below is my two docker file:
docker/test/Dockerfile:
FROM node:lts
RUN mkdir /usr/src/app
WORKDIR /usr/src/app
ENV PATH /usr/src/app/node_modules/.bin:$PATH
RUN wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add -
RUN sh -c 'echo "deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google.list'
RUN apt-key update && apt-get update && apt-get install -y google-chrome-stable
COPY . /usr/src/app
RUN npm install
CMD sh ./docker/test/docker-entrypoint.sh
docker/dev/Dockerfile:
FROM node:lts as dev-builder
ARG CONFIG_S3_BUCKET_URI
ARG S3_FILE_NAME
ARG AWS_SESSION_TOKEN
ARG AWS_DEFAULT_REGION
ARG AWS_SECRET_ACCESS_KEY
ARG AWS_ACCESS_KEY_ID
RUN apt-get update
RUN apt-get install python3-dev -y
RUN curl -O https://bootstrap.pypa.io/get-pip.py
RUN python3 get-pip.py
RUN pip3 install awscli --upgrade
RUN mkdir /app
WORKDIR /app
COPY . .
RUN aws s3 cp "$CONFIG_S3_BUCKET_URI/$S3_FILE_NAME" src/environments/environment.dev.ts
RUN cat src/environments/environment.dev.ts
RUN npm install
RUN npm run build-dev
FROM nginx:stable
COPY nginx.conf /etc/nginx/nginx.conf
COPY --from=dev-builder /app/dist/ /usr/share/nginx/html/
Every time it takes 20-25 mins to build the images.
Is there any way I can optimize the docker file for a better build process?
suggestion are welcome. RUN npm run build-dev uses package.json to install the dependencies. which is one on the reason that it install all dependency for every build.
Thanks
You can use combination of base images and multi stage builds to speed up your builds.
Base image with pre-installed packages/dependencies
Stuff like installing python3, pip, google-chrome, awscli etc need not be done every build. These layers might get cached if you are building on single machine but if you have multiple build machines or clean the cache, you will be re-building these layers unnecessarily. You can build a base image which already has these stuff and use this new image as the base for your app.
Multi stage builds
You are copying your source code and then doing npm install. Even if package.json has not changed, the layer will be re-built if any other file in source code might have changed.
You can create a multi stage dockerfile where you just copy the package.json in the first stage and run npm install and other such commands. This layer will be re-built only if package.json is changed.
In your second stage, you can just copy the npm cache from first stage.
FROM node:lts as dev-builder
WORKDIR /cache/
COPY package.json .
RUN npm install
RUN npm run build-dev
FROM NEW_BASE_IMAGE_WITH_CHROME_ETC_DEPENDENCIES
COPY --from=node_cache /cache/ .
COPY . .
<snip>
Identify any other such optimisations that you can make.
Hi I have a docker file which is failing on the COPY command. It was running fine initially but then it suddenly crashed during the build process. The Docker file basically sets up the dev environment and authenticate with GCP.

Any leads in this would be helpful.
How are you running docker build command?
In docker best practices I've read that docker fails if you try to build your image from stdin using -
Attempting to build a Dockerfile that uses COPY or ADD will fail if this syntax is used. The following example illustrates this:
# create a directory to work in
mkdir example
cd example
# create an example file
touch somefile.txt
docker build -t myimage:latest -<<EOF
FROM busybox
COPY somefile.txt .
RUN cat /somefile.txt
EOF
# observe that the build fails
...
Step 2/3 : COPY somefile.txt .
COPY failed: stat /var/lib/docker/tmp/docker-builder249218248/somefile.txt: no such file or directory
I've reproduced issue... Here is my Dockerfile:
FROM alpine:3.7
## ENV Variables
ENV PYTHON_VERSION="3.6.5"
ENV BUCKET_NAME='detection-sandbox'
ENV DIRECTORY='/usr/local/gcloud'
# working directory
WORKDIR /usr/src/app
COPY kk.txt ./ \
kk.2.txt ./
If I create image by running docker build -t testImage:1 [DOCKERFILE_FOLDER], docker creates image and works correctly.
However if I try the same command from stdin as:
docker build -t test:2 - <<EOF
FROM alpine:3.7
ENV PYTHON_VERSION="3.6.5"
ENV BUCKET_NAME='detection-sandbox'
ENV DIRECTORY='/usr/local/gcloud'
WORKDIR /usr/src/app
COPY kk.txt ./ kk.2.txt ./
EOF
I get the following error:

It seems that docker build images from /var/lib/docker/tmp/ if you build image from stdin, thus ADD or COPY commands don't work.
Incorrect path in source is a common error.
Use
COPY ./directory/testproject-264512-9de8b1b35153.json /dir/
instead of
COPY testproject-264512-9de8b1b35153.json /dir/

~/m/rosdocker
I need it to run catkin_make (which is on the path set up by .bashrc)
Exit code 127 from shell commands means "command not found". Is .bashrc executable? Normally it is not, probably you want to source it?
source ./home/$USERNAME/.bashrc
As Dan Farrel pointed out in his comment, sourcing the file in a RUN command will only have effect within that shell.
To source .bashrc during the build
If you want it to have effect for later commands in the build you need to run them all in the same RUN statement. In the below .bashrcis sourced in the same shell as catkin_make is run.
RUN . /home/ros/.bashrc && \
cd /home/$USERNAME/catkin_ws && \
catkin_make
To source the .bashrc file when the container starts
What should happen when the container is run using docker runis specified using the ENTRYPOINTstatement. If you just want a plain bash prompt, specify /bin/bash. The shell will be run with the user specified in the USER statement.
So in summary if you add the following to the end of your Dockerfile
USER ros
ENTRYPOINT /bin/bash
When someone runs the container using docker run -it <containerName> they will land in a bash shell as the user ros. Bash will automatically source the /home/ros/.bashrc file and all definitions inside will be available in the shell. (Your RUN statement containing the .bashrc file canbe removed

It doesn't look like Docker can find the nlu directory. Are you sure it exists? Are you sure that you are executing the command from the correct directory?
But you also aren't installing Rasa at all or any of it's requirements. Is there a reason you aren't using the pre-built Rasa images? available here with docs here.
