Setting environment variables

Edit online

The IBM® Cloud Infrastructure Center CLI needs several pieces of information about the IBM® Cloud Infrastructure Center deployment in order to work. You can provide this information by using CLI arguments, but it is easier to set environment variables before you use the CLI. IBM® Cloud Infrastructure Center includes the /opt/ibm/icic/icicrc file to simplify this task.

The icicrc file comes configured with default values that match your IBM® Cloud Infrastructure Cloud environment. It does not set the administrator's username or password.

Follow these steps to edit the icicrc file:

Copy the file to your user's home directory and edit it as necessary. In particular, set these values:
- OS_USERNAME - Your username
- OS_PASSWORD - Your password
- OS_PROJECT_NAME - If you have multiple projects, specify the project that you want to access.
- OS_TENANT_NAME - If you have multiple projects, specify the project that you want to access.
Note: If you add your password to this file, restrict the file permission so that other users will not be able to read it. Alternatively, you can choose to not set OS_PASSWORD. In this case, the IBM® Cloud Infrastructure Center CLI prompts you for the password when you run it.

Example:
```
export OS_IDENTITY_API_VERSION=3
export OS_AUTH_URL=https://management_server_IP:5000/v3/
export OS_CACERT=/etc/pki/tls/certs/icic.crt
export OS_REGION_NAME=RegionOne
export OS_PROJECT_DOMAIN_NAME=Default
export OS_PROJECT_NAME=ibm-default
export OS_TENANT_NAME=$OS_PROJECT_NAME
export OS_USER_DOMAIN_NAME=Default
export OS_USERNAME=admin
export OS_PASSWORD=password
export OS_COMPUTE_API_VERSION=2.72
export OS_NETWORK_API_VERSION=2.0
export OS_IMAGE_API_VERSION=2
export OS_VOLUME_API_VERSION=3.60
```
Before you use the IBM® Cloud Infrastructure Center CLI, run source icicrc to set the environment variables.
If administrator runs source icicrc directly without set OS_USERNAME and OS_PASSWORD, a console prompt will ask for username and password.

Example:
```
 [~]# source /opt/ibm/icic/icicrc
 Please input the username: admin
 Please input the password of admin:
```
