s3 backup error : curl: (3) URL using bad/illegal format or missing URL

[patrickstump]

When using the S3 Backup, receiving the following error:

curl: (3) URL using bad/illegal format or missing URL

Possible Cause

The bucket name is ldap01.localdomain which has a .. When I run curl manually, this works fine, however i wonder if with the escaping it is causing an issue.

Config

The following environmental variables are set in my docker-compose file.

      - ENABLE_BACKUP=TRUE
      - BACKUP_INTERVAL=1440
      - BACKUP_RETENTION=10080
      - BACKUP_COMPRESSION=BZ
      - BACKUP_COMPRESSION_LEVEL
      - BACKUP_TYPE=S3
      - S3_BUCKET='ldap01.localdomain'
      - S3_HOST='s3.localdomain'
      - S3_KEY_ID="ldap01"
      - S3_KEY_SECRET="BIGPASSWORDHERE"
      - S3_PATH='openldap-backup'
      - S3_PROTOCOL='https'

Figured it out.
Do NOT put environmental variable in quotes in the docker-compose.yml file.
Bad:

      - S3_BUCKET='ldap01.localdomain'
      - S3_HOST='s3.localdomain'
      - S3_KEY_ID="ldap01"
      - S3_KEY_SECRET="BIGPASSWORDHERE"
      - S3_PATH='openldap-backup'
      - S3_PROTOCOL='https'

Good:

      - S3_BUCKET=ldap01.localdomain
      - S3_HOST=s3.localdomain
      - S3_KEY_ID=ldap01
      - S3_KEY_SECRET=BIGPASSWORDHERE
      - S3_PATH=openldap-backup
      - S3_PROTOCOL=https
