This extends the original configurability of the provider by adding both a baseUrl, which may be your CDN URL, which replaces the endpoint returned from AWS with a custom URL, and prefix, which does exactly that: prefixes the object's path such that we do not strictly upload into the buckets root directory. This can be used to keep the bucket organized.
Everything else follows the regular strapi-provider-upload-aws-s3 schema.
Your configuration is passed down to the provider. (e.g: new AWS.S3(config)). You can see the complete list of options here
See the using a provider documentation for information on installing and using a provider. And see the environment variables for setting and using environment variables in your configs.
To upload with ACLs, make sure that the S3 user has abilities "s3:PutObjectACL" in addition to the regular "s3:PutObject" ability. Otherwise S3 will reject the upload with "Access Denied".
If you cannot provide access key and secret, but instead use other (AWS) tools to authenticate to your bucket, omit providerOptions.accessKeyId and providerOptions.secretAccessKey. For more, see zoomoid#14.
./config/plugins.js
module.exports = ({ env }) => ({
// ...
upload: {
provider: "aws-s3-advanced",
providerOptions: {
accessKeyId: env("AWS_ACCESS_KEY_ID"),
secretAccessKey: env("AWS_ACCESS_SECRET"),
region: env("AWS_REGION"),
params: {
bucket: env("AWS_BUCKET"), // or "Bucket", @aws-sdk requires capitalized properties, but the convention for this file is lowercased, but the plugin understands both
acl: env("AWS_BUCKET_ACL"), // or "ACL", see above
},
baseUrl: env("CDN_BASE_URL"), // e.g. "https://cdn.example.com", this is stored in strapi's database to point to the file
prefix: env("BUCKET_PREFIX"), // e.g. "strapi-assets". If BUCKET_PREFIX contains leading or trailing slashes, they are removed internally to construct the URL safely
},
},
// ...
});If using strapi >= 4.0.0, please use the below config:
./config/plugins.js
module.exports = ({ env }) => ({
// ...
upload: {
config: {
provider: "strapi-provider-upload-aws-s3-advanced",
providerOptions: {
accessKeyId: env("AWS_ACCESS_KEY_ID"),
secretAccessKey: env("AWS_ACCESS_SECRET"),
region: env("AWS_REGION"),
params: {
bucket: env("AWS_BUCKET"), // or "Bucket", @aws-sdk requires capitalized properties, but the convention for this file is lowercased, but the plugin understands both
acl: env("AWS_BUCKET_ACL"), // or "ACL", see above
},
baseUrl: env("CDN_BASE_URL"), // e.g. "https://cdn.example.com", this is stored in strapi's database to point to the file
prefix: env("BUCKET_PREFIX"), // e.g. "strapi-assets". If BUCKET_PREFIX contains leading or trailing slashes, they are removed internally to construct the URL safely
},
},
},
// ...
});If you need to extend the configuration of the S3 client with additional properties, put them into providerOptions.params. The params object is spread into the S3 configuration at initialization, so it will accept any
additional configuration this way.
Note: If you are migrating from a pre-4.0.0 version (i.e. v3.6.8 or earlier), the
filesrelation will includeaws-s3-advancedas the provider. Previously, the prefix "strapi-upload-provider" was assumed to always be present for upload provider plugins. This is no longer the case in >= 4.0.0, hence when uploading with the newer version of this provider, strapi will insert new files with the full provider package name, i.e.,strapi-provider-upload-aws-s3-advanced. See Migration for details on the required manual work.
To allow the thumbnails to properly populate, add the below config to
./config/middlewares.js
module.exports = ({ env }) => [
// ...
{
name: "strapi::security",
config: {
contentSecurityPolicy: {
useDefaults: true,
directives: {
"connect-src": ["'self'", "https:"],
"img-src": ["'self'", "data:", "blob:", `${env("CDN_BASE_URL")}`],
"media-src": ["'self'", "data:", "blob:", `${env("CDN_BASE_URL")}`],
upgradeInsecureRequests: null,
},
},
},
},
// ...
];To allow for an empty baseUrl (#9), we made some adjustments to the way the configuration is parsed: in your plugins.js, env("CDN_BASE_URL") uses strapi's helper function for parsing ENV variables. If any second argument is omitted,
undefined is returned. Thus, if your ENV does not contain any value for CDN_BASE_URL, you are good to go. Undefined baseUrl causes the plugin to prepend the cannonic default endpoint of your storage provider, e.g., https://mystoragebucket.s3.amazonaws.com.
If instead you defined CDN_BASE_URL to be "", the env helper returns that empty string. Previously, this was treated as the same case as using undefined. In some scenarios however you might not want this, e.g., local development. Thus, we now check explicitly for undefinedness instead of the prior truthiness.. If you defined CDN_BASE_URL to be an empty string and relied upon the prepending of the cannonical default endpoint, change your ENV variable either explicitly to the endpoint's URL or make it undefined.
Strapi now uses the full package name as provider name, as seen in the configuration of the provider in the Example section above. This means that the relation will include different provider names when using the newer version of this provider with strapi >= 4.0.0 on data from pre-4.0.0. In particular, you will find that the pre-4.0.0 files will have the provider aws-s3-advanved, while the newer ones will have strapi-provider-aws-s3-advanved. If you're not going to change the existing files in your CDN, you will not need to take any actions. The provider attribute is only used for mapping the handler for creating or deleting files to the handlers defined in this provider. Files will remain readable with the old provider and new files will be added with the new provider name. Only if you want to delete old files from the new provider, you will be required to adapt the files table.
In strapi >= 4.0.0, only SQL databases are officially supported, so we will only provide queries for the supported backends:
UPDATE files SET provider = 'strapi-provider-upload-aws-s3-advanced' WHERE provider = 'aws-s3-advanced';UPDATE `files` SET `provider` = `strapi-provider-upload-aws-s3-advanced` WHERE `provider` = `aws-s3-advanced`;UPDATE files SET provider = 'strapi-provider-upload-aws-s3-advanced' WHERE provider = 'aws-s3-advanced';
