I'm trying to use scp to copy a large file over to cloud shell.
Using the suggested command from this SO answer
gcloud alpha cloud-shell scp \
localhost:~/Sites/my-app/big_file cloudshell:~/big_file
But even though I can see it adding a key for the server, it fails with Permission denied (publickey).
If I do
gcloud alpha cloud-shell ssh
it logs in to the server just fine
Turns out google's invocation of scp was omitting the correct username.
Solution I successfully uploaded by doing
/usr/bin/scp -P 6000 -i /Users/me/.ssh/google_compute_engine -o \
StrictHostKeyChecking=no ~/Sites/my-app/bigfile \
cj@35.185.184.136:~/big_file
How to figure this out
I was able to discover this using the --verbosity debug flag
# gcloud alpha cloud-shell scp --verbosity debug localhost:~/Sites/my-app/big_file cloudshell:~/big_file
DEBUG: Running [gcloud.alpha.cloud-shell.scp] with arguments: [(cloudshell|localhost):DEST: "cloudshell:~/big_file", (cloudshell|localhost):SRC:1: "['localhost:~/Sites/my-app/big_file']", --verbosity: "debug"]
DEBUG: Running command [/usr/bin/scp -P 6000
-i /Users/chrisjensen/.ssh/google_compute_engine
-o StrictHostKeyChecking=no
~/Sites/my-app/big_file 35.185.184.136:~/big_file].
[...more debug info...]
^ This is the line that shows the command that was run
Then I ran ssh to see if there was a difference in the arguments
gcloud alpha cloud-shell ssh --verbosity debug
DEBUG: Running [gcloud.alpha.cloud-shell.ssh] with arguments: [--verbosity: "debug"]
DEBUG: Running command [/usr/bin/ssh -t -p 6000
-i /Users/chrisjensen/.ssh/google_compute_engine
-o StrictHostKeyChecking=no cj@127.0.0.1].
[...more debug info...]
^ Notice it prepends by username to the server ip.
So then I copied the scp command and added my username, and it worked a charm.
Hope this helps others trying to figure this out.
This should be fixed in the latest version of gcloud, which you can get by runnign gcloud components update. Thanks for trying the alpha!
