The following Dockerfile few lines suppose to install curl inside the nginx custom image to run under ubuntu.The second group of code is an attempt to convert the task to do the same but to run on Amazon Linux.

Any suggestion as to what would be the yum equivalent to the rest of the apt-get command?-no-install-recommends curl && rm -rf /var/lib/apt/lists/*

Docker allows you to package an application with its environment and all of its dependencies into a 'box', called a container. Usually, a container consists of an application running in a stripped-to-basics version of a Linux operating system. Now you can call your app using curl (install if needed via: sudo apt-get install curl): $ curl-i. The typical solution is to create a new network in docker, run both containers on that network, and connect via docker's included DNS to the container or service name of the destination, e.g.

if you're asking how to get the Amazon Linux-based Dockerfile to install curl without prompting you, you can add -y to yum update:

How can I get curl installed in ubuntu:1604 image, docker run -it ubuntu:16.04 bash. When I get the # prompt, however I'm unable to run curl command, I just get this error: bash: curl: command docker images Pull the nginx web server, using the docker pull command: docker pull nginx This will pull the latest official nginx Docker image. If you run docker images again, you’ll see the nginx image: Find Unofficial nginx Images. Alternatively, if you don’t want to install the official nginx image, use docker search to find other nginx

-no-install-recommends curl

should be

--no-install-recommends curl

you forgot to put double-dash

How to install packages inside a docker Ubuntu image?, After installing Ubuntu image on docker I tried to run packages inside the image. I get an error to locate package curl How do I solve this? NGINX and Docker are tools that work extremely well together. By using the NGINX open-source image from the Docker Hub repository, you can easily spin up new instances of NGINX in Docker containers. You can also take these images and easily create new Docker images from them to give you even more control of your containers and how you manage them.

For Nginx image use Debian as OS use below : -

Deploying NGINX and NGINX Plus on Docker, To generate an NGINX Plus image: Create the Docker build instruction to install a specific release curl . && apt-get remove --purge --auto-remove -y && rm -rf /var/lib/apt/lists/* How do I install the latest node inside a docker ubuntu 15.10 container? apt-get install nodejs installs version 0.1 and no npm Thanks

Deploy NGINX and NGINX Plus with Docker, Learn how to use the NGINX image from the Docker Hub repository and how to create your own To launch an instance of NGINX running in a container and using the default NGINX curl --unix-socket /var/run/docker-sock Step 1. Starting up nginx-proxy to hook Docker and Nginx together. To get started, let’s start up the nginx-proxy container. This can be accomplished either by a single docker command, or using docker-compose. Let’s cover both. To get started, create a Docker network

Unable to install CURL on Docker Ubuntu image, It seems like you can't access those resources because the DNS are not configured. Check if you have access to them (ping 8.8.8.8) and then This image allows running arbitrary commands like Bash scripts, docker commands and also Docker Compose commands like docker-compose build and docker-compose push. As several Continuous Integration systems allow doing previous steps, like installing packages before running the actual main script, those steps could be used to install Docker Compose.

How To Run Nginx in a Docker Container on Ubuntu 16.04 , Whether you use the open source NGINX image from the Docker Hub Docker containers enable developers to focus their efforts on sudo curl -sSL https://get.​docker.com/ | sh By default, containers are not accessible from the Internet, so we need to map the container's internal port to the Droplet's port. Around a year and a half ago I got Docker Compose working with this image, which is also based on the clue/docker-ttrss image. The author was around to fix an issue with PHP from a few months ago, so that was good.

• No, that is not what I am asking. The question is in regards to the rest of the apt-get command which installed recommended dependencies. Also you put the -y after yum then after install in the second command.
• no, there is no analog to 'recommended' dependencies when using yum like there is with apt-get. have you tried running the second Dockerfile build?

When creating a Dockerfile, there are two commands that you can use to copy files/directories into it – ADD and COPY. Although there are slight differences in the scope of their function, they essentially perform the same task.

So, why do we have two commands, and how do we know when to use one or the other?

In this article, we explain each command, analyze Docker ADD vs COPY, and tell you which one to use.

Let’s start by noting that the ADD command is older than COPY. Since the launch of the Docker platform, the ADD instruction has been part of its list of commands.

The command copies files/directories to a file system of the specified container.

The basic syntax for the ADD command is:

It includes the source you want to copy (<src>) followed by the destination where you want to store it (<dest>). If the source is a directory, ADD copies everything inside of it (including file system metadata).

For instance, if the file is locally available and you want to add it to the directory of an image, you type:

ADDcan also copy files from a URL. It can download an external file and copy it to the wanted destination. For example:

An additional feature is that it copies compressed files, automatically extracting the content in the given destination. This feature only applies to locally stored compressed files/directories.

Type in the source and where you want the command to extract the content as follows:

Bear in mind that you cannot download and extract a compressed file/directory from a URL. The command does not unpack external packages when copying them to the local filesystem.

Note: The ADDcommand extracts a compressed source only if it is in a recognized compression format which is solely based on the contents of the file (not on the file name). The recognized compression formats include identity, gzip, bzip, and xz.

Due to some functionality issues, Docker had to introduce an additional command for duplicating content – COPY.

Unlike its closely related ADD command, COPY only has only one assigned function. Its role is to duplicate files/directories in a specified location in their existing format. This means that it doesn’t deal with extracting a compressed file, but rather copies it as-is.

The instruction can be used only for locally stored files. Therefore, you cannot use it with URLs to copy external files to your container.

To use the COPY instruction, follow the basic command format:

Docker Curl Localhost

For example:

Docker Curl Command

Why was there a need to add a new, similar command?

The fact that ADD had so many functionalities proved to be problematic in practice, as it behaved extremely unpredictable. The result of such unreliable performance often came down to copying when you wanted to extract and extracting when you wanted to copy.

Docker couldn’t completely replace the command due to its many existing usages. To avoid backward compatibility, the safest option was to add the COPY command – a less diverse yet more reliable command.

Considering the circumstances in which the COPY command was introduced, it is evident that keeping ADD was a matter of necessity. Docker released an official document outlining best practices for writing Dockerfiles, which explicitly advises against using the ADD command.

Docker’s official documentation notes that COPY should always be the go-to instruction as it is more transparent than ADD.

If you need to copy from the local build context into a container, stick to using COPY.

The Docker team also strongly discourages using ADD to download and copy a package from a URL. Instead, it’s safer and more efficient to use wget or curl within a RUN command. By doing so, you avoid creating an additional image layer and save space.

Let’s say you want to download a compressed package from a URL, extract the content, and clean up the archive.

Instead of using ADD and running the following command:

You should use:

Note: The only time you would need to use the ADD command is when extracting local tar files into the image.

To sum up – use COPY. As Docker itself suggests, avoid the ADD command unless you need to extract a local tar file.
