--- title: Hugo Deploy description: Upload your site to GCS, S3, or Azure categories: [hosting and deployment] keywords: [deployment,s3,gcs,azure] menu: docs: parent: hosting-and-deployment weight: 20 weight: 20 toc: true --- You can use the "hugo deploy" command to upload your site directly to a Google Cloud Storage (GCS) bucket, an AWS S3 bucket, and/or an Azure Storage container. ## Assumptions * You have completed the [Quick Start] or have a Hugo website you are ready to deploy and share with the world. * You have an account with the service provider ([Google Cloud](https://cloud.google.com/), [AWS](https://aws.amazon.com), or [Azure](https://azure.microsoft.com)) that you want to deploy to. * You have authenticated. * Google Cloud: [Install the CLI](https://cloud.google.com/sdk) and run [`gcloud auth login`](https://cloud.google.com/sdk/gcloud/reference/auth/login). * AWS: [Install the CLI](https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-install.html) and run [`aws configure`](https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-configure.html). * Azure: [Install the CLI](https://docs.microsoft.com/en-us/cli/azure/install-azure-cli) and run [`az login`](https://docs.microsoft.com/en-us/cli/azure/authenticate-azure-cli). * NOTE: Each service supports alternatives for authentication, including using environment variables. See [here](https://gocloud.dev/howto/blob/#services) for more details. * You have created a bucket to deploy to. If you want your site to be public, be sure to configure the bucket to be publicly readable as a static website. * Google Cloud: [create a bucket](https://cloud.google.com/storage/docs/creating-buckets) and [host a static website](https://cloud.google.com/storage/docs/hosting-static-website) * Amazon S3: [create a bucket](https://docs.aws.amazon.com/AmazonS3/latest/gsg/CreatingABucket.html) and [host a static website](https://docs.aws.amazon.com/AmazonS3/latest/userguide/WebsiteHosting.html) * Microsoft Azure: [create a storage container](https://docs.microsoft.com/en-us/azure/storage/blobs/storage-quickstart-blobs-portal) and [host a static website](https://learn.microsoft.com/en-us/azure/storage/blobs/storage-blob-static-website) ## Configuring your first deployment In the configuration file for your site, add a `[deployment]` section and a `[[deployment.targets]]` subsection. The only required parameters are the name and URL: ```toml [deployment] [[deployment.targets]] # An arbitrary name for this target. name = "production" # URL specifies the Go Cloud Development Kit URL to deploy to. Examples: URL = "" # Google Cloud Storage -- see https://gocloud.dev/howto/blob/#gcs #URL = "gs://" # Amazon Web Services S3; see https://gocloud.dev/howto/blob/#s3 # For S3-compatible endpoints, see https://gocloud.dev/howto/blob/#s3-compatible #URL = "s3://?region=" # Microsoft Azure Blob Storage; see https://gocloud.dev/howto/blob/#azure #URL = "azblob://$web" ``` ## Deploy To deploy to a target: ```bash hugo deploy [--target=] ``` The deploy process recursively walks through your local publish directory (`public` by default) and syncs it to the destination bucket, to ensure that the local and remote contents match. If you don't specify a target, Hugo will deploy to the first target in your configuration. See `hugo help deploy` or [the deploy command-line documentation][commandline] for more command-line options. ### How the file list works The first thing `hugo deploy` does is create file lists for local and remote by traversing the local publish directory and remote bucket. For both local and remote, the file list includes and excludes files according to the [deployment target's configuration][config] -- * If the configuration specifies an `include` pattern, all files are skipped by default except those matching the pattern. * If the configuration specifies an `exclude` pattern, files matching the pattern are skipped. {{% note %}} When creating the local file list, a few additional skips apply: first, Hugo always skips files named `.DS_Store`. Second, Hugo always skips local hidden directories (directories with names starting with a period, e.g. `.git`) and does not traverse into them, except for the special [hidden directory named `.well-known`](https://en.wikipedia.org/wiki/Well-known_URI), which is traversed if it exists. {{% /note %}} ### How the local and remote file lists are compared In the second step, Hugo compares the two file lists to figure out what changes actually need to be made on the remote. File names are compared first; if the local and remote files both exist then the sizes and md5sums are compared. Any difference means that the file will be (re-)uploaded. Specifying the `--force` flag will ensure all files are re-uploaded even if Hugo cannot detect any differences between local and remote. Files are deleted from the remote bucket if they are not present in the local file list. {{% note %}} If a remote file is excluded from the file list generation using the exclude/include configs, then the comparison step will not know to delete the file -- so it will remain on the remote even if it isn't present locally. {{% /note %}} If the [`--confirm` or `--dryRun` flags][commandline] are given, Hugo displays what differences it has found and either pauses or stops here. ### How synchronization works Hugo applies the list of changes to the remote storage bucket. Missing and/or changed files are uploaded, and files missing locally but present remotely are deleted. As files are uploaded, their headers are also configured on the remote according to the matchers configuration. {{% note %}} As a safety measure to help prevent accidents, if there are more than 256 files to delete, Hugo won't delete any files from the remote. Use the `--maxDeletes` command line flag to override this. {{% /note %}} ## Advanced configuration Here's a full example deployment configuration: ```toml [deployment] # By default, files are uploaded in an arbitrary order. # If you specify an `order` list, files that match regular expressions # in this list will be uploaded first, in the specified order. order = [".jpg$", ".gif$"] [[deployment.targets]] # Define one or more targets, e.g., staging and production. # Each target gets its own [[deployment.targets]] section. # An arbitrary name for this target. name = "mydeployment" # The Go Cloud Development Kit URL to deploy to. Examples: URL = "" # GCS; see https://gocloud.dev/howto/blob/#gcs #URL = "gs://" # S3; see https://gocloud.dev/howto/blob/#s3 # For S3-compatible endpoints, see https://gocloud.dev/howto/blob/#s3-compatible #URL = "s3://?region=" # Azure Blob Storage; see https://gocloud.dev/howto/blob/#azure #URL = "azblob://$web" # You can use a "prefix=" query parameter to target a subfolder of the bucket: #URL = "gs://?prefix=a/subfolder/" # If you are using a CloudFront CDN, deploy will invalidate the cache as needed. #cloudFrontDistributionID = "" # Include or exclude specific files when deploying to this target: # If exclude is non-empty, and a local or remote file's path matches it, that file is not synced. # If include is non-empty, and a local or remote file's path does not match it, that file is not synced. # Note: local files that don't pass the include/exclude filters are not uploaded to remote, # and remote files that don't pass the include/exclude filters are not deleted. # # The pattern syntax is documented here: https://godoc.org/github.com/gobwas/glob#Glob # Patterns should be written with forward slashes as separator. # #include = "**.html" # would only include files with ".html" suffix #exclude = "**.{jpg, png}" # would exclude files with ".jpg" or ".png" suffix ####################### [[deployment.matchers]] # Matchers enable special caching, content type and compression behavior for # specified file types.
