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:
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
Use the following to get the actual secret key decoded (after copying your encoded key to a file encrypted_key.txt:
$ 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.
kosmas:terraform (add_vault *%)$ packer --version 1.0.4
So after installing the latest version the above error goes away
kosmas:terraform (add_vault *%)$ packer --version 1.6.1
You are trying to build a QEMU image with Packer, but you are getting the error suggesting to use the PACKER_LOG=1 option. But there is no indication where to place it in the command line.
Put it at the begging of the command line as folows:
kosmas:terraform (add_vault *%)$ PACKER_LOG=1 packer build vault_orchestration/template.json
