inotify-tools | C library and a set of command-line programs | File Utils library

Yesterday I tried to install Ejabberd first through souce code, and then with Ubuntu specific packages. I guess I made a mess, because now I'm getting this threatening Crash dump error.

I am running webpack-dev-server inside of a Docker container. For development purposes, I have a local directory bound to the Docker container. It's my understanding that webpack's standard "watch" abilities don't work inside Docker, or at least with volumes bound to the host machine.

But if I turn on polling (watchOptions.poll: true), the Docker container uses a lot of CPU. I can turn down polling to 1000ms or even 5000ms, but that still uses non-negligable amounts of CPU, enough so that my laptop's fans start spinning.

Are there any best practices around limiting CPU usage by a polling webpack-dev-server? Is there anything I can install inside my Linux-based Docker container? I've tried installing the latest inotify-tools, but that doesn't seem to have done the trick.

I hope I've spelled correctly.

I developed a frontend application with reactjs. I distribute the application I developed with docker-compose. But while distributing, I encounter an error like below. Can you help to solve this?

Error https://ibb.co/YtYywBr

Operating System: Ubuntu 18 lts Node Version: v12.16.3 NPM Version: 6.14.4 webpack Version: - webpack-dev-server Version: - Browser: Chrome, opera

An error caused by webpack. How can I get rid of this error?

This is a bug

Code

docker-compose.yml

I am following the cryptonote starter about creating a cryptocurrency on its own blockchain. So far so good except that it doesn't compile. I tried both on Ubuntu 18.04 and 16.04 and I am getting the same error. After creating the code as specified in the guidance, I leave the genesis address and click on compile.

When I run make I am getting this error:

I'm trying to run a simple Tomcat8 server on my Ubuntu 16.04 Docker image. But I can't see the Tomcat default page.

1) I ran this command to run the container docker run -it --entrypoint bash e36658dffbd8

2) I opened up localhost:8080/ after installing tomcat8 in my container but it doesn't work.

Here is my Dockerfile

I wanted to try Docker as a tool for local development — I used docker-compose to spin up 3 containers: one for the database (postgres), front-end (running webpack and node sass in watch mode) and backend (Elixir/Phoenix).

Everything works great, except that when I hit localhost:4000 the page load is really slow — 10-15 seconds just to get the login page, which is static.

I checked the logs from docker-compose and the server response times are fast as usual, which to me it means that something is slowing down the connection to the container.

When I ran the server directly in the Terminal again, everything is pretty fast, e.g. takes 1s to load the same page.

I'm new to Docker so I suspect I might be missing something configuration-wise. Any ideas are appreciated. Thank you!

Configuration

docker-compose.yml

I am facing a problem with a script I need to use for log analysis; let me explain the question:

I have a gzipped file like:

Below is my Dockerfile my-docker-file.

I am working in a Docker container which is being created from CentOS 6. This is basically how the Dockerfile looks like:
