There situations in the dev environment where it would be useful to see server logs, have database access, or rails console access. This should not be used in other environments.
The following assumed you have the cloudfoundry CLI set up on your machine, and have logged in. When you log in, you should select the dev space. Instructions can be found here
If you need to change space, for example to move between the dev space and the staging space you can use the following commands.
To view available spaces:
cf spaces
To change to a different space:
cf target -s <space_name>
To view logs, you will first need to know the service name. cf a will list services, but the service name will probably be ecf-dev.
To view recent logs:
cf logs --recent <app_name>
To tail logs (view them as they are generated)
cf logs <app_name>
You will need to have the psql command on your path for this to work.
For a Debian/Ubuntu based system, this can be achieved with sudo apt-get install postgresql-client-12
On mac, installing through homebrew with brew install postgres is probably easiest. Alternative instructions here.
The first time you try this, you will need to install the conduit plugin:
cf install-plugin conduit
You can list the services with cf s, but the service name will generally be ecf-postgres-dev. For interactive access, use:
cf conduit ecf-postgres-dev -- psql
First, ssh into the host instance
cf ssh <app_name>
Then,
cd /app
and finally
/usr/local/bin/bundle exec rails console
Find the instance guid
GUID=$(cf app ecf-production-worker --guid)
Generate a single use login code
cf ssh-code | [xsel|pbcoby]
Perform the SCP command
scp -P 2222 -o StrictHostKeyChecking=no -oHostKeyAlgorithms=+ssh-rsa -o User=cf:${GUID}/0 [from] [to]
using the password from cf ss-code
e.g.
scp -P 2222 -o StrictHostKeyChecking=no -oHostKeyAlgorithms=+ssh-rsa -o User=cf:${GUID}/0 ssh.london.cloud.service.gov.uk:/app/*.csv .
In cases where the is more than one instance, change the /0 to match the desired instance number
