Uploading packages

In the previous sections, we built several packages in our computer, those packages are stored in the conan local cache, typically ~/.conan/data. Now, you might want to upload them to a conan server for later reuse on another machine, project, or for sharing them.


If you are just evaluating conan, you can create an account on https://bintray.com and create a Conan repository, or you can run a conan server.

The rest of this doc will assume you are uploading the packages to your local server.

First, check if the remote you want to upload to is already in your current remotes:

$ conan remote list

You can add any remote easily. For a remote running in your machine, you could run:

$ conan remote add local http://localhost:9300

You can search any remote in the same way you search your computer. Actually, many conan commands can specify a specific remote.

$ conan search -r=local

Now, upload the package recipe and all the packages to your remote. In this example we are using our local remote, but you could use any other, including conan.io, which often is the default one:

$ conan upload Hello/0.1@demo/testing --all -r=local

You might be prompted for a username and password. The default conan server remote has a demo/demo account we can use for testing.

The --all option will upload the package recipe plus all the binary packages. Now try again to read the information from the remote (we refer to it as remote, even if it is running on your local machine, as it could be run on another server in your LAN):

$ conan search Hello/0.1@demo/testing -r=local


if something fails during the upload, you can try to upload it again. Conan keeps track of the upload integrity and will only upload missing files.

Now we can check if we are able to download and use them in a project. For that purpose, we first have to remove the local copies, otherwise the remote packages will not be downloaded. Since we have just uploaded them, they are identical to the local ones.

$ conan remove Hello*
$ conan search

Since we have our test setup from the previous section, we can just use it for our test. Go to your package folder and run the tests again, now saying that we don’t want to build the sources again, we just want to check if we can download the binaries and use them:

$ conan create demo/testing --no-export --build=never

You will see that the test is built, but the packages are not. The binaries are simply downloaded from your local server. You can check their existence on your local computer again with:

$ conan search
