You would like to tail the Vault auth log files, but if you use the vault tag for auditing and your server is also named vault, you cannot filter out the vault auth logs only.
Use the client_login as the filter in grep:
|
1 |
ubuntu@vault1:~$ sudo tail -f /var/log/auth.log | grep 'client_token' |
You would like to check your haproxy.cfg file for errors when making changes.
Use the following command to validate/check your HAProxy configuration file:
|
1 |
ubuntu@haproxy:~$ sudo haproxy -c -V -f /etc/haproxy/haproxy.cfg |
Problem
You want to use the pgp encryption when using Terraform to create an AWS IAM user, and you have the secret access token returned as an output but encoded.
Solution

|
1 |
$ cat encrypted_key.txt | base64 --decode | gpg -d |
You would like to type some sensitive information in the command line (password, key), but you don’t want this to appear in the history.
Add a single space before the start of the command.
You are trying to add a new workspace in your organization in Terraform Cloud, using the same connected VCS (Gitlab) as the one you already have setup, but you get the above error when trying to add it in Firefox (Linux – Ubuntu – 79).
Use Chromi(um) to create the workspace as it works there. You can then use it in Firefox as normal.
Trying to start the vault server following the guides that specify creating the data directory in /home/vault/data results in the above error and service cannot be started.
According to the guide here: https://learn.hashicorp.com/tutorials/vault/raft-deployment-guide?in=vault/day-one-raft, changing the data directory to /opt/raft and the hcl file to reflect that the server can be started without any errors.
Trying to follow along the example in the Exoscale article about creating custom templates, you get the error about exoscale-import not found, when you are trying to validate the packer template.
Make sure that you use a current packer installation as the exoscale-import was not supported in the older versions.
