# Grabs list of running instances for specified Cosmos component (TEST environment)

# SCP's known log locations from remote to new local directory

Please check the arguments are provided correctly:
|
|
1. cert path (pem)
|
|
2. component name
|
|
3. cosmos user
|
|
|
|
If you have any curl/cert issues try:
|
|
brew install curl --with-openssl
|
|
|
|
If you have any parsing issues try:
|
|
brew install jq
|
|
|
|
If you have any issues with SCP then
|
|
make sure you've given your user SSH access via Cosmos.
|
|
This is something I'd like to automate via this script in future.
