#### Docker build images used by ConanCenterIndex
The Conan Center Index uses [Conan Docker Tools](https://github.com/conan-io/conan-docker-tools/) to build packages in a variety of environments. All images are hosted in [Docker Hub](https://hub.docker.com/u/conanio). The relation of the images with the build configurations is available according to the Conan configuration, as `node_labels.Linux`, for instance:
```yaml
node_labels:
Linux:
x86_64:
"gcc":
default: "linux_gcc_${compiler.version}"
"11": "linux_gcc_${compiler.version}_ubuntu16.04"
"clang":
default: "linux_clang_${compiler.version}_ubuntu16.04"
"11": "linux_clang_${compiler.version}"
```
The configuration files are located in the folder [../.c3i](../.c3i). Currently are the files [config_v1.yml](../.c3i/config_v1.yml) and [config_v2.yml](../.c3i/config_v2.yml). The configuration file `config_v1.yml` is used by the Conan 1.0 client, while `config_v2.yml` is used by the Conan 2.0 client.
The label `linux` refers to any Docker image, while `gcc_${compiler.version}` refers to GCC + a compiler version. For example, `linux_gcc_10` refers to the image `conanio/gcc10`.
The suffix `_ubuntu16.04` refers to the base image used by the Docker image, in this case, `ubuntu16.04`. So, `"11": "linux_gcc_${compiler.version}_ubuntu16.04"` means that the image `conanio/gcc11-ubuntu16.04`. Thus, all GCC versions use `conanio/gcc<version>`, except for the GCC 11, which uses `conanio/gcc11-ubuntu16.04`. The same applies to Clang.
