I had to upload files to an Azure container (An S3 alternative) on a Raspberry Pi for a recent project.
My first choice was to use azcopy; however, it does not support armv7, and after a brief stint at using binfmt and qemu, I opted to use curl.
As a Microsoft product, there are many bad articles on how to do this, and many are for old API versions.
The snippets below are focused on using the smallest amount of headers for x-ms-version: 2019-12-12 and files under 100MB.
FILE_PATH="/path/to/file"
HEADER_MS_DATE=$(TZ=GMT date "+%a, %d %h %Y %H:%M:%S %Z")
HEADER_CONTENT_LENGTH=$(wc --bytes < "${FILE_PATH}")
AZURE_CONTAINERS_URL=https://example.blob.core.windows.net"
AZURE_CONTAINER_NAME=big_box
AZURE_BLOB_PATH_URI="URI/PATH/FOR/FILE.txt"
AZURE_CONTAINER_PATH="${AZURE_CONTAINERS_URL}/${AZURE_CONTAINER_NAME}/${AZURE_BLOB_PATH_URI}"
AZURE_CONTAINER_SAS_TOKEN="sp=racw&st=2022-05-16T17:20:00Z&se=2022-12-05T00:20:00Z&spr=https&sv=2021-01-09&sr=c&sig.."
curl \
--request PUT \
--fail \
--silent \
--header "x-ms-version: 2019-12-12" \
--header "x-ms-date: ${HEADER_MS_DATE}" \
--header "x-ms-blob-type: BlockBlob" \
--header "Content-Length: ${HEADER_CONTENT_LENGTH}" \
--data-binary "@${FILE_PATH}" \
"${AZURE_CONTAINER_PATH}?${AZURE_CONTAINER_SAS_TOKEN}"
If you want to have Azure check your files on upload, you can compute a local md5sum and pass it as a header. Azure will create the md5sum server side if you do not pass this header.
FILE_PATH="/path/to/file"
HEADER_MS_DATE=$(TZ=GMT date "+%a, %d %h %Y %H:%M:%S %Z")
HEADER_CONTENT_LENGTH=$(wc --bytes < "${FILE_PATH}")
HEADER_CONTENT_MD5=$(md5sum -b "${FILE_PATH}" | awk '{ print $1 }' | xxd -p -r | base64)
AZURE_CONTAINERS_URL=https://example.blob.core.windows.net"
AZURE_CONTAINER_NAME=big_box
AZURE_BLOB_PATH_URI="URI/PATH/FOR/FILE.txt"
AZURE_CONTAINER_PATH="${AZURE_CONTAINERS_URL}/${AZURE_CONTAINER_NAME}/${AZURE_BLOB_PATH_URI}"
AZURE_CONTAINER_SAS_TOKEN="sp=racw&st=2022-05-16T17:20:00Z&se=2022-12-05T00:20:00Z&spr=https&sv=2021-01-09&sr=c&sig.."
curl \
--request PUT \
--fail \
--silent \
--header "x-ms-version: 2019-12-12" \
--header "x-ms-date: ${HEADER_MS_DATE}" \
--header "x-ms-blob-type: BlockBlob" \
--header "Content-Length: ${HEADER_CONTENT_LENGTH}" \
--header "Content-MD5: ${HEADER_CONTENT_MD5}" \
--data-binary "@${FILE_PATH}" \
"${AZURE_CONTAINER_PATH}?${AZURE_CONTAINER_SAS_TOKEN}"
