I have the following issue.
Failed to find a valid digest in the 'integrity' attribute for resource 'http://127.0.0.1:8080/uistatic/css/bootstrap4.0.0.min.css' with computed SHA-256 integrity 'xLbtJkVRnsLBKLrbKi53IAUvhEH/qUxPC87KAjEQBNo='. The resource has been blocked.
And this is happening when i put my site into docker with building this Dockerfile:
FROM python:3.6
COPY skfront /app
WORKDIR /app
RUN mkdir -p /static/resources
RUN mkdir logs
RUN mkdir certs
RUN pip3 install -r requirements.txt
RUN python3 manage.py collectstatic --settings blog_site.settings
EXPOSE 8080
CMD python3 website.py -l 0.0.0.0 -p 8080
This css is static file that doesn't change.
Any ideas why this is happening?
I found out that building Dockerfile on Windows can mess-up the final image.
When I build my site under Linux there ware no integrity errors.

I have successfully builded my app and there is image listed my-app:2.7
But when I try to run it error says:
Any idea where is wrong?
docker run -it --rm -p 5000:80 --name my-app:2.7 uploadcore Unable to find image 'uploadcore:latest' locally docker: Error response from daemon: pull access denied for uploadcore, repository does not exist or may require 'docker login': denied: requested access to the resource is denied. See 'docker run --help'.
docker run -p 5000:80 my-app:2.7 Could not execute because the specified command or file was not found. Possible reasons for this include: You misspelled a built-in dotnet command. You intended to execute a .NET program, but dotnet-uploadcore.dll does not exist. You intended to run a global tool, but a dotnet-prefixed executable with this name could not be found on the PATH.
Dockerfile:

Linux is case sensitive, so your ENTRYPOINT has to be
ENTRYPOINT ["dotnet", "UploadCore.dll"]
Your second docker run command works. You can add a container name with the --name option like this
docker run -p 5000:80 --name mycontainer my-app:2.7
The image name has to be the first parameter that isn't an option. In your first docker run command, the first one is uploadcore, so docker looks for an image called that and it can't find it.
I trying to create Docker container to contenerized my Symfony 5 application.
I create first a Dockerfile
FROM php:7.4-fpm-alpine
# Update
RUN apk --no-cache update
RUN apk --no-cache add bash git
# Install Node
RUN apk --no-cache add --update nodejs npm
RUN apk --no-cache add --update python3
RUN apk --no-cache add --update make
RUN apk --no-cache add --update g++
# Install pdo
RUN docker-php-ext-install pdo_mysql
# Install Composer
RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer
# Symfony CLI
RUN curl -sS https://get.symfony.com/cli/installer | bash && mv /root/.symfony/bin/symfony /usr/local/bin/symfony
# WORK DIR
COPY . /var/www/html
WORKDIR /var/www/html
RUN composer update
RUN composer install
RUN npm install
# Start Symfony server on Port 8000
EXPOSE 8000
RUN symfony serve -d
Then I created a docker-compose.yml file (where I simply redirect port 8000 of the container to port 8080 on my machine).
version: '3.8'
services:
php-fpm:
container_name: infolea
build: ./
ports:
- 8080:8000
volumes:
- ./:/var/www/html
Then, I build my image docker-compose build.
Then, I run my image docker-compose up -d.
On my browser, the localhost:8080 link doesn't display anything.
Then I restart the symfony server by typing symfony serve -d on the terminal of my container and on localhost:8080 I can see my application working.
Something is weard, is that when I verified if my server is not started yet on my docker container terminal, I got this :
docker container terminal
What i want, it's to start my Symfony server dirrectly, without retapping symfony serve -d.
How can i do it ?
Try using CMD istead of RUN
CMD ["/usr/local/bin/symfony", "local:server:start" , "--port=8000", "--no-tls"]
see https://docs.docker.com/engine/reference/builder/#cmd
simple use-case to deploy the nginx image using kubernetes
Dockerfile used to create the image. The "./build/" in the dockerfile COPY statement, is the output directory (npm run build) of reactjs code.Just static files in it.
FROM nginx
COPY ./build/ /usr/share/nginx/html/
RUN rm -f /etc/nginx/conf.d/default.conf
COPY ./default.conf /etc/nginx/conf.d/
CMD ["nginx"]
EXPOSE 80
Why is this error in nginx deployment? error is "Back-off restarting failed container".
manually ran the container, but nginx is not running. I could start the nginx manually. Am I missing any configuration in the Dockerfile or in /etc/nginx/conf.d/default.conf file? files are copied and available in github path for reference.
root#desktop:~/github/nginx-app# docker run -it private.registry.corp/company-dev-poc/nginx-cms:001 bash
root#fc7ebd431ae2:/# service nginx status
[FAIL] nginx is not running ... failed!
Use CMD ["nginx", "-g", "daemon off;"]
Also, you do not need to specify the command. CMD and EXPOSE would be defined in the base image - nginx in this case. They need not be defined again.
I have a docker file called quasar.dockerfile. I built the docker file and everything loaded successfully.
#quasar.dockerfile
FROM java:8
WORKDIR /app
ADD docker/quasar-config.json quasar-config.json

apt-get install -y wget && \

EXPOSE 8080
CMD java -jar web_2.11-2.2.3-SNAPSHOT-one-jar.jar -c /app/quasar-config.json
I then tried running the docker and I get this error saying that I am unable to access the jarfile.

Error: Unable to access jarfile web_2.11-2.2.3-SNAPSHOT-one-jar.jar
How come the process keeps getting killed? Seems like it has to do with being unable to run the jarfile but the build needed to access that file and happened successfully. Is this a linking issue?
Try to use full path on Dockerfile
CMD java -jar /web_2.11-2.2.3-SNAPSHOT-one-jar.jar -c /app/quasar-config.json
I am specifically talking about an app bundle running on my own server.
I have a Meteor app running using forever in ~/bundle and my git repo is at ~/project. I keep different release bundle tarballs in ~/release.
~/release
|-0.1.0.tar.gz
|-0.1.1.tar.gz
|-0.2.0.tar.gz
After pulling in changes from git and switching to the latest release, I want to bundle my new version and take advantage of hot-code reloading and (hopefully?) keeping client connections alive. What is the best way to do this?
Note: I am also using nginx; so will this affect the process in any way? i.e. will it kill open client connections? do I have to reload nginx after updating to newer app version?
Thanks.
You could use a script like this.
Make sure define your server in your ssh config file, e.g
Host yourserver
User youruser
Port 22
Hostname yourapp.com
IdentityFile ~/.ssh/yourkeyfile.pem
TCPKeepAlive yes
IdentitiesOnly yes
Then you could have a bash script like this:
#!/bin/bash
cd ~/Desktop/yourappdirectory
rm -f ~/Desktop/yourapp.tar.gz
meteor bundle ~/Desktop/yourapp.tar.gz
scp ~/Desktop/yourapp.tar.gz yourserver:~/yourapp.tar.gz
ssh yourserver <<'ENDSSH'
cd ~/
tar -xzf yourapp.tar.gz
sudo rm -rf yourapp
mv bundle yourapp
cd yourapp/programs/server/node_modules
rm -rf fibers
rm -rf bcrypt
sudo npm install fibers#1.0.1
sudo npm install bcrypt
cd ~/yourapp/programs/server/npm/mongo-livedata/main
rm -r mongodb
sudo npm install mongodb#1.4.1
cd ~/
sudo forever stop ~/yourapp/main.js
sudo MONGO_URL=mongodb://user:pass#ip:27017/meteor PORT=3000 ROOT_URL=https://yoursite.com forever start ~/yourapp/main.js
ENDSSH
Then just run the bash and it would upload and deploy your app for you. Just a note I couldn't put a release version in so stuff just uploads to ~/yourapp.tar.gz then unbundles into ~/yourapp
The meteor app would then be hot code reloaded on any clients if they're on the site.
