8 What is Artifact Repository
9 ---------------------------
11 An Artifact Repository is akin to what Subversion is to source code, i.e. it is a way of versioning artifacts produced by build systems, CI, and so on. [1]
13 Why Artifact Repository is Needed
14 ---------------------------------
16 Since many developers check their source code into the GIT repository it may seem natural to just place the files you've built into the repo too. This can work okay for a single developer working on a project over the weekends but with a team working on many components that need to be tested and integrated, this won't scale.
18 The way git works, no revision of any file is ever lost. So if you ever check in a big file, the repository will always contain it, and a git clone will be that much slower for every clone from that point onward.
20 The golden rule of revision control systems applies: *check in your build scripts, not your build products*.
22 Unfortunately, it only takes one person to start doing this and we end up with huge repositories. Please don't do this. It will make your computers sad. Thankfully, Gerrit and code review systems are a massive disincentive to doing this.
24 You definitely need to avoid storing binary images in git. This is what artifact repositories are for. [2]
26 A “centralized image repository” is needed that can store multiple versions of various virtual machines and have something like /latest pointing to the newest uploaded image. It could be a simple nginx server that stores the output images from any jenkins job if it's successful, for instance.

29 =========================
31 What is used as Artifact Repository for OPNFV
32 ---------------------------------------------
34 Setting up, hosting, and operating an artifact repository on OPNFV Infrastructure in Linux Foundation (LF) environment requires too much storage space. It is also not a straightforward undertaking to have robust Artifact Repository and provide 24/7 support.
36 OPNFV Project decided to use **Google Cloud Storage** as OPNFV Artifact Repository due to reasons summarized above. [3]
38 Usage of Artifact Repository in OPNFV CI
39 ----------------------------------------
41 Binaries/packages that are produced by OPNFV Continuous Integration (CI) are deployed/uploaded to Artifact Repository making it possible to reuse artifacts during later stages of OPNFV CI. Stored artifacts can be consumed by individual developers/organizations as well.
43 In OPNFV, we generally produce PDF, ISO and store them on OPNFV Artifact Repository.
45 OPNFV Artifact Repository Web Interface
46 ----------------------------------------
48 OPNFV Artifact Repository is accessible via link http://artifacts.opnfv.org/.
50 A proxy has been set up by LF for the community members located in countries with access restrictions to Google http://build.opnfv.org/artifacts/.
52 Access Rights to OPNFV Artifact Repository
53 ==========================================
55 As summarized in previous sections, OPNFV uses Google Cloud Storage as Artifact Repository. By default, everyone has read access to it and artifacts can be fetched/downloaded using browser, a curl-like command line HTTP client, or gsutil.
57 Write access to Artifact Repository is given per request basis and all the requests must go through `LF Helpdesk <opnfv-helpdesk@rt.linuxfoundation.org>`_ with an explanation regarding the purpose of write access. Once you are given write access, you can read corresponding section to store artifacts on OPNFV Artifact Repository.
59 How to Use OPNFV Artifact Repository
60 ====================================
62 There are 3 basic scenarios to use OPNFV Artifact repository.
65 * downloading artifacts
68 Please see corresponding sections regarding how to do these.
70 How to Browse Artifacts Stored on OPNFV Artifact Repository
71 -----------------------------------------------------------
73 You can browse stored artifacts using
75 * **Web Browser**: By navigating to the address `OPNFV Artifact Storage <http://artifacts.opnfv.org/>`_.
77 * **Command Line HTTP-client**
78 ``curl -o <output_filename> http://artifacts.opnfv.org``
82 ``curl -o opnfv-artifact-repo.html http://artifacts.opnfv.org``
84 * **Google Storage Util (gsutil)**
85 ``gsutil ls gs://artifacts.opnfv.org/<path_to_bucket>``
89 ``gsutil ls gs://artifacts.opnfv.org/octopus``
91 How to Download Artifacts from OPNFV Artifact Repository
92 --------------------------------------------------------
94 You can download stored artifacts using
96 * **Web Browser**: By navigating to the address `OPNFV Artifact Storage <http://artifacts.opnfv.org/>`_ and clicking the link of the artifact you want to download.
98 * **Command Line HTTP-client**
99 ``curl -o <output_filename> http://artifacts.opnfv.org/<path/to/artifact>``
103 ``curl -o main.pdf http://artifacts.opnfv.org/octopus/docs/release/main.pdf``
105 * **Google Storage Util (gsutil)**
106 ``gsutil cp gs://artifacts.opnfv.org/<path/to/artifact> <output_filename>``
110 ``gsutil cp gs://artifacts.opnfv.org/octopus/docs/release/main.pdf main.pdf``
112 How to Upload Artifacts to OPNFV Artifact Repository
113 ----------------------------------------------------
115 As explained in previous sections, you need to get write access for OPNFV Artifact Repository in order to upload artifacts.
117 Apart from write access, you also need to have Google account and have the Google Cloud Storage utility, **gsutil**, installed on your computer.
119 Install and Configure gsutil
120 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
122 Please follow steps listed below.
126 Please follow steps listed on `this link <https://cloud.google.com/storage/docs/gsutil_install>`_ to install gsutil to your computer.
130 Issue below command and follow the instructions. You will be asked for the project-id. The project-id is **linux-foundation-collab**.
134 3. Request write access for OPNFV Artifact Repository
136 Send an email to `LF Helpdesk <opnfv-helpdesk@rt.linuxfoundation.org>`_ and list the reasons for the request. Do not forget to include gmail mail address.
141 Once you installed and configured gsutil and got write access from LF Helpdesk, you should be able to upload artifacts to OPNFV Artifact Repository.
143 The command to upload artifacts is
145 ``gsutil cp <file_to_upload> gs://artifacts.opnfv.org/<path/to/bucket>``
149 ``gsutil cp README gs://artifacts.opnfv.org/octopus``
151 Once the upload operation is completed, you can do the listing and check to see if the artifact is where it is expected to be.
153 ``gsutil ls gs://artifacts.opnfv.org/<path/to/bucket>``
157 ``gsutil ls gs://artifacts.opnfv.org/octopus``
162 Send an email to `LF Helpdesk <opnfv-helpdesk@rt.linuxfoundation.org>`_ or join the channel **#opnfv-octopus** on IRC.
