Docker doesn’t seem to be working on my AMD Raysen 5 3600 on B450 motherboard. Part 2: El Capitan. Neofetch of Pentium 4 on El Capitan. If you want to install Docker for Mac for free, your computer must have been manufactured in 2010 or later and needs to be running macOS El Capitan 10.11 or higher. If you have Windows 7, Windows 8, or an older Mac, you need to install Docker Toolbox instead of Docker for Windows or Docker for Mac. This download will install the required Hyper. Docker is an open-source project that automates the deployment of applications inside software containers. Docker CE(Community Edition) for Mac is an easy-to-install desktop app for building, debugging, and testing Dockerized apps on a Mac. System requirement Docker for Mac works on OS X El Capitan 10.11 and newer macOS releases. No Comments on Fix Docker not using /etc/hosts on MacOS On my MacBook with Mac OS X 10.11 (El Capitan) and Docker 1.12.0, Docker did not read manually set DNS entries from the /etc/hosts file.

Travis CI builds can run and build Docker images, and can also push images toDocker repositories or other remote storage.
Npm install for example, here we want to install Angular CLI using the NPM package manager on Windows for Node.js app development. So, the command is: For locally: npm install @angular/cli. Fo Globally:-g syntax refers to the global. Npm install -g @angular/cli. Step 9: NPM update command. Commands for NPM will be same for all OS. How to Install Node.js 14 in CentOS, RHEL, and Fedora. The latest version of Node.js and NPM is available from the official NodeSource Enterprise Linux repository, which is maintained by the Nodejs website and you will need to add it to your system to be able to install the latest Nodejs and NPM packages. This example repository runs two Docker containers built from the same image: a Sinatra application; the Sinatra application test suite; After specifying in the.travis.yml to use Docker (with services: - docker) and Ruby (with language: ruby), the beforeinstall build step pulls a Docker image from carlad/sinatra then runs. So I can't get to install npm in alpine linux. I thought perhaps I can just do a apk add npm but apparently apk search npm returns nothing, even after a apk update.I'm experimenting with all this from the nginx:alpine docker image, i.e. Docker run -it nginx:alpine /bin/sh. I can't use npm install using the command prompt in NodeJS. I'm getting these errors when running npm install: module.js:339 throw err; ^ Error: Cannot find module 'semver' at Function.
To use Docker add the following settings to your .travis.yml:
Then you can add - docker commands to your build as shown in the followingexamples.
We do not currently support use of Docker on macOS.
For information on how to use Docker on Travis CI Enterprise check out Enabling Docker Builds.
Using a Docker Image from a Repository in a Build #
This example repository runs twoDocker containers built from the same image:
- a Sinatra application
- the Sinatra application test suite
After specifying in the .travis.yml to use Docker (with services: - docker) and Ruby (with language: ruby), the before_install build step pulls a Docker image from carlad/sinatra then runs
in a container built from that image after mapping some ports and paths. Readthe Docker User Guide if you need arefresher on how to use Docker.
The full .travis.yml looks like this
and produces the following buildoutput:
Building a Docker Image from a Dockerfile #
Instead of downloading the Docker image fromcarlad/sinatra you canbuild it directly from the Dockerfile in the GitHubrepository.
To build the Dockerfile in the current directory, and give it the samecarlad/sinatra label, change the docker pull line to:
The full .travis.yml looks like this
Pushing a Docker Image to a Registry #
To push an image to a Docker registry, one must first authenticate via dockerlogin. The email, username, and password used for login should be stored inthe repository settings environment variables, which may be set up through therepository settings web page or locally via the Travis CLI, e.g.:
Be sure to encrypt environment variablesusing the travis gem.
Within your .travis.yml prior to attempting a docker push or perhaps beforedocker pull of a private image, e.g.:
Branch Based Registry Pushes #
To push a particular branch of your repository to a remote registry,use the custom deploy section of your .travis.yml:
Where docker_push is a script in your repository containing:
Private Registry Login #
When pushing to a private registry, be sure to specify the hostname in thedocker login command, e.g.:
Docker Toolbox El Capitan
Using Docker Compose #
The Docker Compose tool is also installed in the Docker enabled environment.
If needed, you can easily replace this preinstalled version of docker-composeby adding the following before_install step to your .travis.yml:
Docker Npm Install Permission Denied
Installing a newer Docker version #
You can upgrade to the latest version and use any new Docker features by manuallyupdating it in the before_install step of your .travis.yml:
Docker El Capitan Software
Updating from download.docker.com
Alternatively, you can use addons instead of before_install to update via apt as well:
Docker Npm Install Slow
Check what version of Docker you’re running with docker --version
Docker Npm Install Not Working
Examples #
Docker Npm Install Timeout
- heroku/logplex (Heroku log router)
- kartorza/docker-pg-backup (A cron job that will back up databases running in a docker PostgreSQL container)
Question or issue on macOS:
Docker newbie here. I’m using a Mac Book Pro with 128Gb disk. Is there any way to have the docker images be stored in an external hard drive rather than on the mac’s main drive? I don’t have that much free space, and can’t afford to remove any installed software. Ideally I’d like to have Docker fetch the images from an external drive. Can this be done using a symlink?
Thanks
How to solve this problem?
Solution no. 1:
Eventually figured out that docker can use a symlink. In a Mac OS setup the file that I want to place in an external drive is located at
~/Library/Containers/com.docker.docker/Data/com.docker.driver.amd64-linux/
and is named
Docker.qcow2
Just move the file to an external disk drive (for instance) and create a symlink pointing to the new location
Solution no. 2:
I was able to get this working and documented it here. It is basically a symlink to the folders mentioned.
