If you have access to your web host with SSH, you can use a simple rsync one-liner to incrementally deploy your entire Hugo website.
The spoiler is that you can deploy your entire website with a command that looks like the following:
|
|
As you will see, we’ll put this command in a shell script file, which makes building and deployment as easy as executing ./deploy
.
To make logging in to your server more secure and less interactive, you can upload your SSH key. If you have already installed your SSH key to your server, you can move on to the next section.
First, install the ssh client. On Debian distributions, use the following command:
install-openssh.sh
|
|
Then generate your ssh key. First, create the .ssh
directory in your home directory if it doesn’t exist:
|
|
Next, execute this command to generate a new keypair called rsa_id
:
|
|
You’ll be prompted for a passphrase, which is an extra layer of protection. Enter the passphrase you’d like to use, and then enter it again when prompted, or leave it blank if you don’t want to have a passphrase. Not using a passphrase will let you transfer files non-interactively, as you won’t be prompted for a password when you log in, but it is slightly less secure.
To make logging in easier, add a definition for your web host to the file ~/.ssh/config
with the following command, replacing HOST
with the IP address or hostname of your web host, and USER
with the username you use to log in to your web host when transferring files:
|
|
Then copy your ssh public key to the remote server with the ssh-copy-id
command:
|
|
Now you can easily connect to the remote server:
|
|
Now that you can log in with your SSH key, let’s create a script to automate deployment of your Hugo site.
Create a new script called deploy
the root of your Hugo tree:
|
|
Add the following content. Replace the USER
, HOST
, and DIR
values with your own values:
|
|
Note that DIR
is the relative path from the remote user’s home. If you have to specify a full path (for instance /var/www/mysite/
) you must change ~/${DIR}
to ${DIR}
inside the command-line. For most cases you should not have to.
Save and close, and make the deploy
file executable:
|
|
Now you only have to enter the following command to deploy and update your website:
|
|
Your site builds and deploys:
|
|
You can incorporate other proprocessing tasks into this deployment script as well.
