If the system uses a slow network connection, then yum may require some time to download the repository and find the indexes and the header files for each package. The yum utility will search for data to determine the best repository and proceeds with the required installation and will show the result to display the transaction for you.
The result may include the installations, updates, or removal of the packages, in order to resolve and install the software dependencies.
It will review the list of changes and packages needed to upgrade, and when we press y to accept and begin the process. If you press N or Enter, then yum will not download or change any packages. The yum will only display and uses the newest version of the package, unless we specify about installing the older version. The yum also imports the repository of public keys if it is not installed on the RPM keyring. You can enable them alongside the stable repository. The followingcommand enables the nightly repository.
You can disable the nightly or test repository by running the yum-config-manager command with the --disable flag. To re-enable it, usethe --enable flag. The following command disables the nightly repository. Install the latest version of Docker Engine and containerd, or go to the next step to install a specific version:. If you have multiple Docker repositories enabled, installingor updating without specifying a version in the yum install or yum update command always installs the highest possible version,which may not be appropriate for your stability needs.
To install a specific version of Docker Engine, list the available versionsin the repo, then select and install:. List and sort the versions available in your repo. This example sorts results by version number, highest to lowest, and is truncated:. The list returned depends on which repositories are enabled, and is specificto your version of CentOS indicated by the. Install a specific version by its fully qualified package name, which is the package name docker-ce plus the version string 2nd column starting at the first colon : , up to the first hyphen, separated by a hyphen -.
For example, docker-ce This command downloads a test image and runs it in a container. When thecontainer runs, it prints a message and exits.
This installs and runs Docker Engine. Use sudo to run Dockercommands. Continue to Linux postinstall to allownon-privileged users to run Docker commands and for other optional configurationsteps. To upgrade Docker Engine, follow the installation instructions,choosing the new version you want to install. You need to downloada new file each time you want to upgrade Docker Engine. To install a nightly or test pre-release package,change the word stable in the above URL to nightly or test.
Learn about nightly and test channels. Install Docker Engine, changing the path below to the path where you downloadedthe Docker package. Docker is installed but not started. The docker group is created, but nousers are added to the group. Use sudo to run Docker commands. The convenience script is not recommended for production environments, but can beused as an example to create a provisioning script that is tailored to your needs.
Also refer to the install using the repositorysteps to learn about installation steps to install using the package repository. The source code for the script is open source, and can be found in the docker-install repository on GitHub. Always examine scripts downloaded from the internet before running them locally. Before installing, make yourself familiar with potential risks and limitationsof the convenience script:. This example downloads the script from get.
Docker is installed. The docker service starts automatically on Debian baseddistributions. As the message indicates, non-root users cannot run Docker commands by default. The installation script requires root or sudo privileges to install anduse Docker. If you want to grant non-root users access to Docker, refer to thepost-installation steps for Linux.
Docker can also be installed without root privileges, or configured to runin rootless mode. For instructions on running Docker in rootless mode, refer torun the Docker daemon as a non-root user rootless mode. Docker also provides a convenience script at test. This script is equivalent to thescript at get. Use this script toget early access to new releases, and to evaluate them in a testing environmentbefore they are released as stable.
If you installed Docker using the convenience script, you should upgrade Dockerusing your package manager directly. There is no advantage to re-running theconvenience script, and it can cause issues if it attempts to re-addrepositories which have already been added to the host machine. Images, containers, volumes, or customized configuration files on your hostare not automatically removed. To delete all images, containers, andvolumes:.

Installation using Composer The easiest way to create a new Zend Framework project is to use Composer. To create your new Zend Framework project: Once installed, you can test it out immediately using PHP's built-in web server: This will start the PHP cli-server on port , and bind it to all network interfaces.
Note: The built-in CLI server is for development only. Using Vagrant This skeleton includes a Vagrantfile based on Ubuntu Start it up using: Once built, you can also run composer within the box. The container environment is named 'zf', so you will pass that value to docker-compose run : Gitea provides automatically updated Docker images within its Docker Hub organization.
Ports To bind the integrated openSSH daemon and the webserver on a different port, adjustthe port section. Named volumes To use named volumes instead of host volumes, define and use the named volumewithin the docker-compose. Startup To start this setup based on docker-compose , execute docker-compose up -d ,to launch Gitea in the background.
Installation After starting the Docker setup via docker-compose , Gitea should be available using afavorite browser to finalize the installation. This should be changed. The overlay2 storage driver is recommended. Uninstall old versions Older versions of Docker were called docker or docker-engine.
