linode-cli does not work in a shell script
I have a shell script that is set up something like this:
#!/usr/bin/env sh
set -x
MY_SERVER_AUTORIZED_KEY=${MY_SERVER_AUTORIZED_KEY:-$(cat ~/.ssh/id_rsa.pub)}
linode_id=$( \
linode-cli linodes create \
--image "linode/debian9" \
--label my-server \
--root_pass "${MY_SERVER_ROOTPW}" \
--booted true \
--region us-west \
--type g6-standard-4 \
--stackscript_id 607433 \
--authorized_keys "\"${MY_SERVER_AUTORIZED_KEY}\"" \
--text --format 'id' --no-headers \
)
echo $linode_id
When I run this on my local computer, I get the following error:
Request failed: 400
authorized_keys SSH Key 1 key-type must be ssh-dss, ssh-rsa, ecdsa-sha2-nistp, or ssh-ed25519.
The thing is that when I run directly on the command line the same linode-cli command that gets printed due to my "set -x" I get a successful result. What am I doing wrong here?

When I tested this script in my local environment, I received the same error. After some testing, I found that this syntax allows the Linode to be created:
#!/usr/bin/env sh
set -x
Key=$( cat ~/.ssh/id_rsa.pub )
MY_SERVER_AUTORIZED_KEY="$Key"
linode_id=$( \
linode-cli linodes create \
--image "linode/debian9" \
--label my-server \
--root_pass "${MY_SERVER_ROOTPW}" \
--booted true \
--region us-west \
--type g6-standard-4 \
--stackscript_id 607433 \
--authorized_keys "$MY_SERVER_AUTORIZED_KEY"
--text --format 'id' --no-headers \
)
echo $linode_id
Saving the contents of id_rsa.pub into a separate variable before calling it makes the syntax easier to manage, but there's probably a way to combine both variables. I did also want to make a suggestion with regards to the Linode label, since when I was testing this script, I got an error stating "Label must be unique among your Linodes". You can avoid that by accepting input for --label the way you did for root password, or by creating a loop that iterates over subsequent numbers (i.e. my-server-1, my-server-2, etc.)
Thanks! I ended up settling on this syntax:
#!/usr/bin/env sh
set -x
RTMP_SERVER_AUTORIZED_KEY_FILE=${RTMP_SERVER_AUTORIZED_KEY_FILE:-"~/.ssh/id_rsa.pub"}
linode_id=$( \
linode-cli linodes create \
--image "linode/debian9" \
--label my-server \
--root_pass "${MY_SERVER_ROOTPW}" \
--booted true \
--region us-west \
--type g6-standard-4 \
--stackscript_id 607433 \
--authorized_keys "$(cat $RTMP_SERVER_AUTORIZED_KEY_FILE)" \
--text --format 'id' --no-headers \
)
echo $linode_id
There was just something about putting the key contents into an environment variable that just didn't work. I never quite figured it out. However, having a file path in the environment variable works perfectly, so I just used that.
Concerning the label, the above is just example code the demonstrated the issue. My actual code is a little more sophisticated with this. But thanks!
