tsuru-admin command supports administrative operations on a tsuru server. It can be compiled with:
$ go get github.com/tsuru/tsuru-clients/tsuru-admin
To use tsuru-admin commands you should be an admin user. To be an admin user you should be in an admin team.
Setting a target¶
The target for the tsuru-admin command should point to the listen address configured in your tsuru.conf file.
$ tsuru-admin target-add default tsuru.myhost.com:8080 $ tsuru-admin target-set default
All the “container*”” commands below only exist when using the docker provisioner.
$ tsuru-admin containers-move <from host> <to host>
It allows you to move all containers from one host to another. This is useful when doing maintenance on hosts. <from host> and <to host> must be host names of existing docker servers. They can either be added to the docker:servers entry in the tsuru.conf file or added dynamically if using other schedulers, see docker schedulers for more details.
This command will go through the following steps:
- Enumerate all units at the origin host;
- For each unit, create a new unit at the destination host;
- Erase each unit from the origin host.
$ tsuru-admin container-move <container id> <to host>
This command allow you to specify a container id and a destination host, this will create a new container on the destination host and remove the container from its previous host.
$ tsuru-admin containers-rebalance [--dry]
Instead of specifying hosts as in the containers-move command, this command will automatically choose to which host each unit should be moved, trying to distribute the units as evenly as possible.
The –dry flag runs the balancing algorithm without doing any real modification. It will only print which units would be moved and where they would be created.
All the “platform*”” commands below only exist when using the docker provisioner.
$ tsuru-admin platform-add <name> [--dockerfile]
This command allow you to add a new platform to your tsuru installation. It will automatically create and build a whole new platform on tsuru server and will allow your users to create apps based on that platform.
The –dockerfile flag is an URL to a dockerfile which will create your platform.
$ tsuru-admin platform-update <name> [--dockerfile]
This command allow you to update a platform in your tsuru installation. It will automatically rebuild your platform and will flag apps to update platform on next deploy.
The –dockerfile flag is an URL to a dockerfile which will update your platform.
