Write bash script to install cloudstorage

[KatiRG]

Eventually to be incorporated into the main ckan install script ckan_install.sh.

Note: currently using an un-merged branch of cloudstorage while waiting for it to be finalized...

I was unable to insert a string containing the escape character \ into ckan.ini using the helper fn replace_str_in_file() -- the escape character always gets omitted.

As a work-around, the string containing the escape character is stored in a text file snippet, and the snippet is then appended to ckan.ini in the appropriate place:

# Escape special characters in Azure secret with str_to_sed_str() and duplicate any % chars
AZURESECRET_FORMATTED=$(str_to_sed_str $(sed '/%/s/$/%%/' <<<$AZURESECRET))
# Store formatted Azure secret in a text file
echo "\"${AZURESECRET_FORMATTED}\"" > secret_snippet.txt
# Add secret to ckan.ini by appending text file
sed -i '/"secret":/ r secret_snippet.txt' $CKANINI
rm secret_snippet.txt

However...this appends the secret in a new line which will cause an error:

File "<unknown>", line 3
    "secret":
            ^
SyntaxError: unexpected EOF while parsing

Issue with escape characters resolved:

function replace_str_in_ckan_ini() {
    ORIGINAL_STR=`str_to_sed_str "$1"`
    REPLACEMENT_STR=`str_to_sed_str "$2"`
    sed -i -r 's/'"$ORIGINAL_STR"'/'"$REPLACEMENT_STR"'/' $CKANINIPATH
}

export SECRET_ESCAPED=$(str_to_sed_str $(sed '/%/s/$/%%/' <<<$AZURESECRET))
replace_str_in_ckan_ini "<access key 1>" "$SECRET_ESCAPED" "$CKANINIPATH"
