Error message: 'ssh: Could not resolve hostname true: Name or service not known' #8

Closed oveits closed 6 years ago

We can see that 2_docker...sh runs fine until the ansible-playbook finisches (failed=0). However, after that an ssh command seems to fail.

Log:

ansible-playbook -i $DIR/inventory --become --private-key=${key_path} $DIR/openshift-ansible/playbooks/byo/config.yml | tee $DIR/2_install_openshift_via_ansible.log

The problem is caused by the line

# file: 2_install_openshift_via_ansible.sh
...
MASTERIP=`cat ./terraform.tfstate | grep public_ip | awk -F '"' '{print $4; exit}'`

returning true instead of an IP address.

We will see, why:

$ cat ./terraform.tfstate | grep public_ip
                            "associate_public_ip_address": "true",
                            "public_ip": "35.156.2.76",
                            "associate_public_ip_address": "true",
                            "public_ip": "35.156.161.11",
                            "associate_public_ip_address": "true",
                            "public_ip": "35.156.161.17",
                            "map_public_ip_on_launch": "true",

I need to make sure that I only get the value of public_ip, but not the value of associate_public_ip_address.

This is better:

cat ./terraform.tfstate | grep '"public_ip"'

Trying: 

$ MASTERIP=`cat ./terraform.tfstate | grep '"public_ip"' | awk -F '"' '{print $4; exit}'`
$ echo $MASTERIP
35.156.2.76

Perfect!
