Top 10 Repository Management Devops Tools

Introduction:

Software development in the today’s world depends on two things, namely – our own source code and additional binary components. Binary components to understand it perfectly, it can be understood as the output of any intermediate step in your actual development process. Most common examples for the binary components are the JAR, WAR, EAR packages in the Java world and these can vary as we vary with the Programming language itself. Most of the Organizations would want to setup their DevOps process based on their build tool and then comes the need of a Repository Management tool that handles all such requirements. There are various kinds of options available in the market that can take up the responsibilities of a Repository Manager (either we can choose for a free open source version or we could go pro with a paid version, this helps mature the whole DevOps process in your Organization).

With this common understanding let us now go through the various available options that we can see in the DevOps space of Repository Management.

1. Helix Core Version Control:
The next product in the listing for the day is Helix Core Version Control which is based on the Versioning engine that powers Perforce customers who see lightning fast, file level asset management. Helix Core, formerly known as Perforce Helix is the version control engine for the large scale development environments. It manages a centralized database and also along with it a master repository of all possible file versions.

Helix Core clients are classified into 5 categories (based on the way that they connect to the Code repository): GIT, Command, GUI, Web and Plugin. Perforce system can make a portion or all of its content made available as GIT repositories. Users of GIT and of other clients can make use of this and work with the same file content and history. GIT commits will be further be visible to others as Perforce Changelists and the other way round for others.

Following are some of the advantages of using Helix Core Version Control, let us now take a look at each and every one of them:

Advantages:

• Users can work remotely from any part of the world, pulling only the files that they require
• Users can add a lock over files in order to prevent overwrites on binaries
• Users can set granular permissions to the file level for having complete control
• Users will be ensured consistent performance even when the repositories scale further
• Users will be having global visibility, as in, which files are checked-out by which users and etc.
• Users are provided the best of the tools to identify differences in the files that they work on parallel before commits
• It simplifies and also automates the branching best practices
• It provides a pretty good search functionality, which scans on your entire repository for any content that you are currently interested in.

5. Pulp:
Pulp, a platform that is specifically designed to manage repositories of software packages to be made available for a large number of consumers to consume. Pulp can locally mirror small part or all parts of the repository, host your own software packages in repositories and also manage various kinds of content from various sources to a single and a centralized place. Pulp as a tool has its plugin integrations with softwares like RPM, Python, Puppet, Docker and also OSTree. To be very precise, the primary focus was on software packages such as RPMs and / or Puppet modules. 

There are few core capabilities of Pulp as like syncing and publishing to the repositories have been implemented in a rather generic way so that it can be extended further by the plugins to support specific content types. Since the design of Pulp is flexible enough, Pulp can be extended further to nearly any type of digital content. The most important feature of Pulp is that it makes it very easy for the third party plugins to be written and deployed separately from the Pulp platform. Any of the new plugins that are installed on Pulp, it detects these and activates them automatically.

• You can push your content to consumer machines and tracking what each of these consumers have installed.
• Publish your content as a web-based repository, to a series of ISOs, or in any other way that meets your needs.

7. NuGet:
NuGet is the official package manager for .NET managed by the Outercurve Foundation. The original purpose to have a repository manager is to organize on your binary components that the development team relies upon and to maintain it properly. The whole idea of committing these along with your source code beats the purpose of using any Repository Managers and hence NuGet comes into use. The NuGet workflow has been put in place to commit the packages folder into source control with the reasoning that if they don’t have NugGet, they might end up dumping all these binaries into the source control only for the reason to allow others to build the whole application code.

Following are some of the advantages of using NuGet, let us now take a look at each and every one of them:

Advantages:

• NuGet ensures taking the responsibility of dependency chains and version conflicts at the installation time.
• NuGet also facilitates installing, uninstalling, updating, removing packages at the application level.
• NuGet can act more than just a package manager, but also as a protocol for other means because of its extensibility, tooling and also because of its integration capabilities.
• NuGet also ensures better performances, application security.
• NuGet is lightweight, improved and reduced servicing.

8. MyGet:
There are scenarios where MyGet gets to be implemented quite differently from NuGet or the like and the scenarios as like:

• Any specific feed that contains only the packages that an individual or an Organization uses often.
• Any specific feed that only a specific open source project or its dependencies uses.
• Any specific feed that contains a few packages which you want to use for a certain project and all the developers of the project are instructed to install and use them.
• Any specific feed that creates or pushes packages on itself by polling your GitHub or Codeplex or Bitbucket repositories and then triggering their build services.

With that discussed, let us now take a look at the difference that is observed between MyGet and NuGet. With MyGet, there is a possibility to setup the feed less than 5 seconds and all this can be done without even setting up any of our own infrastructure. There is only one feed per account in NuGet whereas with MyGet you can have multiple feeds per account. It also allows you to delegate privileges to others without even sharing an API key as everyone would be having their own API key and secure access to MyGet.

Following are some of the advantages of using MyGet, let us now take a look at each and every one of them:

Advantages:

• One of the best advantages using MyGet is that you get to have multiple feeds per account whereas you get only one feed per account with NuGet.
• Setting up a feed is all done without even having your own infrastructure.
• You don’t see any network latency only for the first time where the package mirroring is triggered.
• We are covered against any upstream source availability issues.

npm is said to open up a new world of JavaScript talent to individuals and teams. It is the world’s largest software registry which contains over 6 million packages or building blocks of code. It is helpful when open source developers from every part of the world use it to share and borrow packages. The packages are all put in such a manner that will enable you to keep track of all the dependencies and the specific versions of it. 

There are three components to npm, they are the website, registry and the cli. The npm website is the place where developers discover packages, set up their profiles and also manage the other aspects of npm. The npm registry is the huge database that contains all the dependencies and stuff whereas the npm cli is the one that is used by most of the developers to interact with npm.

Following are some of the advantages of using npm, let us now take a look at each and every one of them:

Advantages:

• With npm, you can adapt packages to your specific applications without any hassles.
• You can download and use standalone tools then and there itself.
• You can share your code with any other user who again uses npm.
