The config install
is intended to share the Conan client configuration. For example, in a company or organization,
is important to have common settings.yml
, profiles
, etc.
It can get its configuration files from a local or remote zip file, from a local directory or from a git repository. It then installs the files in the local Conan configuration.
The configuration may contain all or a subset of the allowed configuration files. Only the files that are present will be replaced. The only exception is the conan.conf file for which only the variables declared will be installed, leaving the other variables unchanged.
This means for example that profiles and hooks files will be overwritten if already present, but no profile or hook file that the user has in the local machine will be deleted.
All the configuration files will be copied to the Conan home directory. These are the special files and the rules applied to merge them:
File |
How it is applied |
---|---|
profiles/MyProfile |
Overrides the local ~/.conan/profiles/MyProfile if already exists |
settings.yml |
Overrides the local ~/.conan/settings.yml |
remotes.txt |
Overrides remotes. Will remove remotes that are not present in file |
config/conan.conf |
Merges the variables, overriding only the declared variables |
hooks/my_hook.py |
Overrides the local ~/.conan/hooks/my_hook.py if already exists |
The file remotes.txt is the only file listed above which does not have a direct counterpart in the ~/.conan folder. Its format is a list of entries, one on each line, with the form of
[remote name] [remote url] [bool]
where [bool]
(either True
or False
) indicates whether SSL should be used to verify that remote. The remote definitions can be
found in the remotes.json file and it provides a helpful starting point when writing the remotes.txt to be packaged in
a Conan client configuration.
Note
During the installation, Conan skips any file with the name README.md or LICENSE.txt.
The conan config install <item> calls are stored in a config_install.json file in the Conan local cache. That allows to issue a conan config install command, without arguments, to iterate over the cached configurations, executing them again (updating).
The conan config install can be periodically executed, before any command, when config_install_interval is configured in conan.conf. Conan runs it based on config_install.json, including the timestamp of the last change.
Examples:
Install the configuration from a URL:
$ conan config install http://url/to/some/config.zip
Install the configuration from a URL, but only getting the files inside a origin folder inside the zip file, and putting them inside a target folder in the local cache:
$ conan config install http://url/to/some/config.zip -sf=origin -tf=target
Install configuration from 2 different zip files from 2 different urls, using different source and target folders for each one, then update all:
$ conan config install http://url/to/some/config.zip -sf=origin -tf=target $ conan config install http://url/to/some/config.zip -sf=origin2 -tf=target2 $ conan config install http://other/url/to/other.zip -sf=hooks -tf=hooks # Later on, execute again the previous configurations cached: $ conan config install
It’s not needed to specify any argument, it will iterate previously stored configurations in config_install.json, executing them again.
Install the configuration from a Git repository with submodules:
$ conan config install http://github.com/user/conan_config/.git --args "--recursive"
You can also force the git download by using --type git (in case it is not deduced from the URL automatically):
$ conan config install http://github.com/user/conan_config/.git --type git
Install from a URL skipping SSL verification:
$ conan config install http://url/to/some/config.zip --verify-ssl=False
This will disable the SSL check of the certificate.
Install the configuration from a local path:
$ conan config install /path/to/some/config.zip
List all previously installed origins (the ones that will be used if conan config install is called without args):
$ conan config install --list
This will display the list of stored origins, with their index inside the list.
Remove one of the previously installed origins:
$ conan config install --remove=1
This will remove the element with index=1 (second element in the list) of the existing origins. This means that the next conan config install manual or scheduled calls to this command will not use this origin anymore.
